Unary Operator

Example of Unary operator and Use of Final keyword

package basic;

public class Unaryoperator
	public static void main(String[] args)
	int a=1;
	// a++ means post increment "use current value a then inrement value of a"
	// here current value is 1
	System.out.println(a++);//then value become 2
	//++a is pre-increment means "first increment value of a then use it"
	int i=0,j=0;
	j=i++; //0
	System.out.println("i value :"+i);
	System.out.println("j value :"+j);
    //let's see use of final keyword
	//it is used define constant
	final int x=12;
