Java – Variable

Java variables are piece of memory that can store data values. A variable is assigned with a data type.

Java – JVM Architecture

The JVM (Java Virtual Machine) is an abstract machine. This is a specification that provides a runtime environment that can execute the Java bytecode.

Java – JDK, JRE and JVM

Java – Set Path in Java

PATH is a system variable that the operating system uses to find the required executable file from the command line or terminal window.

Java – First Java program

To create a simple Java program, you must create a class because Java is an object-oriented language, so you must write some code inside a class. The class contains the main method. On this page, we will learn how to write the simple Java program after installing JDK and configuring the path.

Java – Internal Representation Of Program

In Java, programs are not compiled into executable files,they are compiled into bytecode , then JVM (Java Virtual Machine) executes this at runtime. Java source code is compiled into bytecode when we use javac compiler. Bytecode is stored on disk with a file extension like .class.

Java – C++ & Java Comparison

There are many differences and similarities between the C ++ and Java programming language. Below is a list of the main differences between C ++ and Java.
