Answer:
The process of Java programming can be simplified in three steps:
Create the program by typing it into a text editor and saving it to a file – HelloWorld.java.
Compile it by typing “javac HelloWorld.java” in the terminal window.
Execute (or run) it by typing “java HelloWorld” in the terminal window.
Below is the simplest program of Java printing “Hello World” to the screen.
/* This is a simple Java program.
FileName : "HelloWorld.java". */
class HelloWorld
{
// Your program begins with a call to main().
// Prints "Hello, World" to the terminal window.
public static void main(String args[])
{
System.out.println("Hello, World");
}
}
Output:
Hello, World
