It is intended to let application developers "write once, run ananywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to rurun on another. Java applications ns are typically compiled to bytecode (class file) that can run on anany Java virtual machine (JVM)) regardless of computer architecture. Java is, as of 2014, one of tthe most popular programming ng languages in use, particularly for client-server web applications, witwith a reported 9 million developers.[10][11] Java was originallyy developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems'Micros Java platform. -
Q. What Is Java ? Java Is a Programming Language and A
GANDHI CHOWK Q. What is Java ? Java is a programming language and a platform. Java is a high level, robust, secured and object-oriented programming language. Platform: Any hardware or software environment in which a program runs, is known as a platform. Since Java has its own runtime environment (JRE) and API, it is called platform. Where it is used? According to Sun, 3 billion devices run java. There are many devices where java is currently used. Some of them are as follows: 1. Desktop Applications such as acrobat reader, media player, antivirus etc. 2. Web Applications such as irctc.co.in, javatpoint.com etc. 3. Enterprise Applications such as banking applications. 4. Mobile 5. Embedded System 6. Smart Card 7. Robotics 8. Games etc. TYPES OF JAVA APPLICATIONS There are mainly 4 type of applications that can be created using java programming: 1) Standalone Application It is also known as desktop application or window-based application. An application that we need to install on every machine such as media player, antivirus etc. AWT and Swing are used in java for creating standalone applications. 2) Web Application An application that runs on the server side and creates dynamic page, is called web application. Currently, servlet, jsp, struts, jsf etc. technologies are used for creating web applications in java. Ishwar Prakash(8271395373) 1 GANDHI CHOWK 3) Enterprise Application An application that is distributed in nature, such as banking applications etc. It has the advantage of high level security, load balancing and clustering. In java, EJB is used for creating enterprise applications. -

Difference between java se development kit and java update // Check if "Hello.java" exists using list (ls) command. Java SE 10 (18.3) (JDK 10) (March 2018): Introduced var for type inference local variable (similar to JavaScript). Introduced time-based release versioning with two releases each year, in March and September, denoted as YY.M. Removed native-header generation tool javah. See " JDK 10 New Features ". Java SE 7 (JDK 7) (July 2011): First version after Oracle purchased Sun Microsystem - aslo called OracleJDK. Introduced Strings in switch statement, Binary integer literals, allowing underscores in numeric literals, improved type inference for generic instance creation (or diamond operator. Differences between Java EE, Java SE, Java ME and JavaFX.

Jfokus 2020 Current state of EA and Charlie Gracie Java Engineering Group at Microsoft its uses in the JVM Overview • Escape Analysis and Consuming Optimizations • Current State of Escape Analysis in JVM JITs • Escape Analysis and Allocation Elimination in Practice • Stack allocation 2 Escape Analysis and Consuming Optimizations 3 What is Escape Analysis? • Escape Analysis is a method for determining the dynamic scope of objects -- where in the program an object can be accessed. • Escape Analysis determines all the places where an object can be stored and whether the lifetime of the object can be proven to be restricted only to the current method and/or thread. 4 https://en.wikipedia.org/wiki/Escape_analysis Partial Escape Analysis • A variant of Escape Analysis which tracks object lifetime along different control flow paths of a method. • An object can be marked as not escaping along one path even though it escapes along a different path. 5 https://en.wikipedia.org/wiki/Escape_analysis EA Consuming Optimizations 1. Monitor elision • If an object does not escape the current method or thread, then operations can be performed on this object without synchronization 2. Stack allocation • If an object does not escape the current method, it may be allocated in stack memory instead of heap memory 3. Scalar replacement • Improvement to (2) by breaking an object up into its scalar parts which are just stored as locals 6 Current State of Escape Analysis in JVM JITs 7 HotSpot C2 EA and optimizations • Flow-insensitive1 implementation based on the
