Write a java program to swap a two integer without using a Temporary Third variable

Program :

class Swap1

{

    public static void main(String[] args) {

       

        int x = 5 ;

        int y = 7 ;

        x = x +  y ;

        y =  x - y ;

        x = x - y ;

        System.out.println("After Swapping " +x);

        System.out.println("Before Swapping " +y);

    }

}

Output :

write a java program to find the greatest number among 2 digit.

program :

class Greatest

{

public static void main(String[] args) {

int x = 5 ;

int y = 7 ;

if (x > y ) {

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

}

else{

System.out.println("Greatest Number is " +y);

}

}

}

Output :

write a Java program to print Fibonacci Series

Program :

class Fibonacci

{

public static void main(String[] args) {

int fs = 10 , a = 0 ,b =1 , c , i ;

System.out.println("Fibonacci Series");

for (i = 1;i<=fs-2 ;i++ )

                 {

                       c= a+b ;

System.out.println(c);

a= b ;

b = c ;

}

}

}

Output :

write a java program to print star design.

program :

class Design
{
public static void main(String args [])
{

System.out.println("* * * * * *");

System.out.println("* * * * * ");

System.out.println("* * * * ");

System.out.println("* * * ");

System.out.println("* * ");

System.out.println("* ");

}
}

Output :
