write a java program to demonstrate used of Math Function round()

 Program :

import java.lang.Math ;

public class RoundFun

{

    public static void main(String[] args) {

       

        double d1 = 201.653 ;

        System.out.println("Round value of d1 : " +Math.round(d1)) ;   

    }

}

Output :

write a java program to demonstrate used of Math Function pow()

Program :

import java.lang.Math ;

public class Power

{

    public static void main(String[] args) {

        double n1 = 2 , n2 = 3;

        System.out.println(+n1 + " ^ " + n2 + " = " +Math.pow(n1 , n2 ));

    }

}

Output :

write a java program to find the largest of two value using Math Function max()

Program :

import java.lang.Math ;

public class Maximum

{

    public static void main(String[] args) {  

 

        int n1 , n2 ;

        n1 = 3 ;

        n2 = 4 ;

        System.out.println("Maximum of " + n1 +" and " + n2 + " is " + Math.max(n1 , n2)) ;

    }

}

Output :

write a java program to demonstrate increment and decrement Operator

 Program :

class IncDec

{

    public static void main(String[] args) {

        int a , b ;

        a = 2 ;

        b = 3 ;

        a++ ;

        ++a ;

        System.out.println("Value of after increment " +a) ;

        --b ;

        b-- ;

        System.out.println("Value of after decrement " +b) ;

    }
}


Output :

Write a java program to find the greatest among Three Number

 Program :

class GreatestThree

{

    public static void main(String[] args) {

        int x = 5 , y = 7 , z = 9 ;

if(x > y && x > z)

System.out.println("x is Greatest");

else

            if(y > x && y > z)

System.out.println("Y is Greatest");

else

System.out.println("Z is Greatest");   

        }

    }

Output :
