Lastly, which is a limited version of a goto statement within loops to make the program jump to another part of the program. Maps the specified key to the specified value. Iteration control allows us to set up that process in code, check out this collection of tutorials and articles on all things Java Collections. This would be true if the loop started at the end of the array and moved toward the beginning. This list contains names of all students in a class. The key is of course unit testing this and seeing that passing lambda creates an interesting twist to the process. In the second iteration, we have looked at every element and remembered the largest. We call it a for each loop because this loop repeats itself by going through each element that is present inside an array or a collection.

  • G, a Language Based on Demand-Driven Stream Evaluations
    AN ABSTRACT OF THE THESIS OF John R. Placer for the degree of Doctor of Philosophy in Computer Science presented on November 4, 1988. Title: C: A Language Based On Demand-Driven Stream Evalutions Redacted for privacy Abstract approved: Timothy Budd A programming paradigm can be defined as a model or an approach employed in solving a problem. The results of the research described in this document demon- strate that it is possible to unite several different programming paradigms into a single linguistic framework. The imperative, procedural, applicative, lambda-free, relational, logic and object-oriented programming paradigms were combined ina language called G whose basic datatype is the stream. A stream is a data object whose values are produced as it is traversed. In this dissertation we describe the methodology we developed to guide the design of G, we present the language G itself, we discuss a prototype implementation of G and we provide example programs that show how the paradigms included in G are expressed. We also present programs that demonstrate some ways in which paradigms can be combined to facilitate the solutions to problems. G : A Language Based On Demand-Driven Stream Evaluations by John R.

  • Control Flow Statements
    Control Flow Statements http://docs.oracle.com/javase/tutorial/java/nutsandbolts/flow.html http://math.hws.edu/javanotes/c3/index.html 1 Control Flow The basic building blocks of programs - variables, expressions, statements, etc. - can be put together to build complex programs with more interesting behavior. CONTROL FLOW STATEMENTS break up the flow of execution by employing decision making, looping, and branching, enabling your program to conditionally execute particular blocks of code. Decision-making statements include the if statements and switch statements. There are also looping statements, as well as branching statements supported by Java. 2 Decision-Making Statements A. if statement if (x > 0) y++; // execute this statement if the expression (x > 0) evaluates to “true” // if it doesn’t evaluate to “true”, this part is just skipped // and the code continues on with the subsequent lines B. if-else statement - - gives another option if the expression by the if part evaluates to “false” if (x > 0) y++; // execute this statement if the expression (x > 0) evaluates to “true” else z++; // if expression doesn’t evaluate to “true”, then this part is executed instead if (testScore >= 90) grade = ‘A’; else if (testScore >= 80) grade = ‘B’; else if (testScore >= 70) grade = ‘C’; else if (testScore >= 60) grade = ‘D’; else grade = ‘F’; C. switch statement - - can be used in place of a big if-then-else statement; works with primitive types byte, short, char, and int; also with Strings, with Java SE7, (enclose the String with double quotes);

  • Chapter 3: Control Statements
    Chapter 3: Control Statements 3.1 Introduction In this chapter, you will learn various selection and loop control statements. Java provides selection statements that let you choose actions with two or more alternative courses. Java provides a powerful control structure called a loop, which controls how many times an operation or a sequence of operation is performed in succession. 3.2 Selection Statements Java has several types of selection statements: if Statements, if … else statements, nested if statements switch Statements Conditional Expressions 3.2.1 Simple if Statements if (booleanExpression) { statement(s); } // execution flow chart is shown in Figure (A) Example if (radius >= 0) { area = radius*radius*PI; System.out.println("The area for the circle of radius " + radius + " is " + area); } // if the Boolean expression evaluates to T, the statements in the block are executed as shown in figure (B) false false Boolean (radius >= 0) Expression true true Statement(s) area = radius * radius * PI; System.out.println("The area for the circle of " + "radius " + radius + " is " + area); (A) (B) FIGURE 3.1 An if statement executes statements if the Boolean Expression evaluates as true Note: The Boolean expression is enclosed in parentheses for all forms of the if statement. Thus, the outer parentheses in the previous if statements are required. Outer parentheses required Braces can be omitted if the block contains a single statement if ((i > 0) && (i < 10)) { Equivalent if ((i > 0) && (i < 10)) System.out.println("i is an " + System.out.println("i is an " + + "integer between 0 and 10"); + "integer between 0 and 10"); } (a) (b) Caution: o Adding a semicolon at the end of an if clause is a common mistake.

  • Iterating in Perl: Loops
    Iterating in Perl: Loops - Computers are great for doing repetitive tasks. - All programming languages come with some way of iterating over some interval. - These methods of iteration are called ‘loops’. - Perl comes with a variety of loops, we will cover 4 of them: 1. if statement and if-else statement 2. while loop and do-while loop 3. for loop 4. foreach loop if statement Syntax: - if the conditional is ‘true’ then the if(conditional) body of the statement (what’s in { between the curly braces) is …some code… executed. } #!/usr/bin/perl -w $var1 = 1333; Output? if($var1 > 10) 1333 is greater than 10 { print “$var1 is greater than 10\n”; } exit; if-else statement Syntax: -if the conditional is ‘true’ then execute if(conditional) the code within the first pair of curly { braces. …some code… } - otherwise (else) execute the code in else the next set of curly braces { …some different code… } Output? #!/usr/bin/perl -w 13 is less than 100 $var1 = 13; if($var1 > 100) { print “$var1 is greater than 100\n”; } else { print “$var1 is less than 100\n”; } exit; Comparisons that are Allowed - In perl you can compare numbers and strings within conditionals - The comparison operators are slightly different for each one - The most common comparison operators for strings: syntax meaning example lt Less than “dog” lt “cat” False! d > c gt Greater than “dog” gt “cat” True! d > c le Less than or equal to “dog” le “cat” False! d > c ge Greater than or equal to “dog” ge “cat” True! d > c eq Equal to “cat” eq “cat” True! c = c ne Not equal to “cat” eq “Cat”

  • Functional Programming Patterns in Scala and Clojure Write Lean Programs for the JVM
    Early Praise for Functional Programming Patterns This book is an absolute gem and should be required reading for anybody looking to transition from OO to FP. It is an extremely well-built safety rope for those crossing the bridge between two very different worlds. Consider this mandatory reading. ➤ Colin Yates, technical team leader at QFI Consulting, LLP This book sticks to the meat and potatoes of what functional programming can do for the object-oriented JVM programmer. The functional patterns are sectioned in the back of the book separate from the functional replacements of the object-oriented patterns, making the book handy reference material. As a Scala programmer, I even picked up some new tricks along the read. ➤ Justin James, developer with Full Stack Apps This book is good for those who have dabbled a bit in Clojure or Scala but are not really comfortable with it; the ideal audience is seasoned OO programmers looking to adopt a functional style, as it gives those programmers a guide for transitioning away from the patterns they are comfortable with. ➤ Rod Hilton, Java developer and PhD candidate at the University of Colorado Functional Programming Patterns in Scala and Clojure Write Lean Programs for the JVM Michael Bevilacqua-Linn The Pragmatic Bookshelf Dallas, Texas • Raleigh, North Carolina Many of the designations used by manufacturers and sellers to distinguish their products are claimed as trademarks. Where those designations appear in this book, and The Pragmatic Programmers, LLC was aware of a trademark claim, the designations have been printed in initial capital letters or in all capitals.

  • Chapter 4 Loops
    Chapter 4 Loops 4.1 Introduction • Loops are structures that control repeated executions of a block of statements. • Java provides a powerful control structure called a loop, which controls how many times an operation or a sequence of operation is performed in succession. • Java provides three types of loop statements while loops, do-while loops, and for loops. 4.2 The while Loop • The syntax for the while loop is as follows: while (loop-continuation-condition) { // loop-body Statement(s); } • The braces enclosing a while loop or any other loop can be omitted only if the loop body contains one or no statement. The while loop flowchart is in Figure (a). • The loop-continuation-condition, a Boolean expression, must appear inside the parentheses. It is always evaluated before the loop body is executed. • If its evaluation is true, the loop body is executed; if its evaluation is false, the entire loop terminates, and the program control turns to the statement that follows the while loop. CMPS161 Class Notes (Chap 04) Page 1 /25 Kuo-pao Yang • For example, the following while loop prints Welcome to Java! 100 times. int count = 0; while (count < 100) { System.out.println("Welcome to Java!"); count++; } count = 0; Loop false false Continuation (count < 100)? Condition? true true Statement(s) System.out.println("Welcome to Java!"); (loop body) count++; (A) (B) FIGURE 4.1 The while loop repeatedly executes the statements in the loop body when the loop-continuation-condition evaluates to true. Caution • Make sure that the loop-continuation-condition eventually becomes false so that the program will terminate.
