Java Key Features : 

Platform Independent Java is independent for following reasons: It depends on the Java Virtual Machine (JVM), code is compiled to bytecode, which is interpreted by the resident JVM, JIT (just in time) compilers attempt to increase speed. With concept of Write-once-run-anywhere (known as the Platform independent) is one of the important key feature of java language Java Key Features

Platform Independent with portable : 

Compile-time Environment Compile-time Environment Java Bytecodes move locally or through network Java Source (.java) Java Compiler Java Bytecode (.class ) Runtime System Class Loader Bytecode Verifier Java Class Libraries Operating System Hardware Java Virtual machine Platform Independent with portable

Java Key Features : 

Object Oriented Language Polymorphism Inheritance Encapsulation Java programs contains definitions and instantiations of classes Everything is encapsulated in a class! Java Key Features

Java Key Features : 

Robust  strong memory allocation and automatic garbage collection. powerful exception handling and type checking. Compiler checks the program for any syntax error. Interpreter checks any run time error and makes the system secure from crash.   Distributed The widely used protocols like HTTP and FTP. Java Key Features

Java Key Features : 

Secure Java does not use memory pointers explicitly. All the programs in java are run under an area known as the sand box. Security manager determines the accessibility options of a class like reading and writing a file to the local disk. Java Key Features

Java Key Features : 

Interpreted and High Performance Java uses native code usage lightweight process called  threads. By using JIT compiler java give high performance in low-power CUP`s Multithreaded It execute instructions according to the program code in a process or a program. Multithreading works the similar way as multiple processes run on one computer. Java Key Features

Slide 9: 

The essential steps to creating and running Java programs go as follows: Create a Java source code file Compile the source code Run the compiled code in a Java Virtual Machine. The Java Procedure

Slide 10: 

These essential elements of Java include: KEYWORDS & SYMBOLS DATA TYPES OPERATORS IDENTIFIERS LITERALS EXPRESSIONS STATEMENTS Java Essentials

Slide 11: 

KEYWORDS & SYMBOLS These keywords, combined with the syntax of the operators and separators, form the definition of the Java language. Java Essentials
