Pre-knowlegde: declare a variable

Initialising a variable is adding a value to an object.

For example:

a = 1
b = 2

in java we do it like this:

STEPS:

1. declare a variable
   package Initialising;
   
   public class initialize {
   
   	void start() {
   		int a;
   		int b;
   	}
   
   	public static void main(String[] args) {
   		new initialize().start();
   	}
   }

2. initialise a variable
   package Initialising;
   
   public class initialize {
   
   	void start() {
   		int a = 1;
   		int b = 2;
   	}
   
   	public static void main(String[] args) {
   		new initialize().start();
   	}
   }

To check your code use the print command:

package Initialising;

public class initialize {

	void start() {
		int a = 1;
		int b = 2;

		System.out.println("a = " + a);
		System.out.println("b = " + b);
	}

	public static void main(String[] args) {
		new initialize().start();
	}
}

OUTPUT:

a = 1
b = 2
