int x=6;

int y=4;

 

System.out.println((x==6)&&(y==3));

System.out.println((x==6)||(y==3));

System.out.println(!(x<y));

}

}

          4. Write a program for Relational Operator

class Comparison{

         public static void main (String args[]){

int x=6;

int y=4;

System.out.println("x  is"+x+",y  is"+y);

System.out.println("x<y="+(x<y));

System.out.println("x<=y="+(x<=y));

System.out.println("x>y="+(x>=y));

System.out.println("x==y="+(x==y));

System.out.println("x!=y="+(x!=y)); 

}

}

          5.Write a program for Conditional Operator

class ConOprDemo

{

public static void main (String args[])

{

int x=25;

int y=10;

int z=0;

//The  smaller value is returned

z=x>y?x:y;

System.out.println("The value is"+z);

     }

}

 

Answer the Following Questions

                                                                             (10 marks)

          1.What is Operator? Write 8 Operator.

Arithmetic Operator:

class ArithmeticTest{

public static void main (String args[]){

short x=6;

int y=4;

float a=12.5f;

float b=7f;

System.out.println("x  is"+x+",y  is"+y);

System.out.println("x+y="+(x+y));

System.out.println("x-y="+(x-y));

System.out.println("x*y="+(x*y));

System.out.println("x/y="+(x/y));

System.out.println("x%y="+(x%y));

System.out.println ("a  is"+a+"b  is"+b);

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

}

}

Assignment Operators:

class AssignDemo{

  public static void main (String args[]){

int a=1;

int b=2;

int c=3;

a+=5;

b*=4;

c+=a*b;

c%=6;

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

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

System. out.println("c="+c);

}

}

Incrementing and Decrementing :

class PrePostFixTest{

public static void main(String  args[]){

       int x=10;

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

       System.out.println("Initial value of X:"+x);

       System.out.println("X value in Println:"+x++);

       System.out.println("After Post increment X:"+x);

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

        x=10;

       System.out.println("Initial value of X:"+x);

        System.out.println("X value in Println:"+ ++x);

       System.out.println("After Post increment X:"+x);

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

}

}

Comparisons   Or  Relational Operator

class Comparison{

         public static void main (String args[]){

int x=6;

int y=4;

System.out.println("x  is"+x+",y  is"+y);

System.out.println("x<y="+(x<y));

System.out.println("x<=y="+(x<=y));

System.out.println("x>y="+(x>=y));

System.out.println("x==y="+(x==y));

System.out.println("x!=y="+(x!=y));

}

}

Logical Operator

class Logical{

         public static void main (String args[]){

int x=6;

int y=4;

 

System.out.println((x==6)&&(y==3));

System.out.println((x==6)||(y==3));

System.out.println(!(x<y));

}

}

Bitwise Operator

class BitwiseDemo

{

public static void main(String args[])

{

int x=10;

int y=20;

int z=30;

x=x | 40;

y>>=1;

z<<=2;

System.out.println("x | 40 :" +x);

System.out.println("y>>1 :" +y);

System.out.println("z<<2 :" +z);

// reinitialize to its original value.

x=10;

z=30;

x=x^z;

System.out.println("x^z:" +z);

}

}

String-concatenation operator

Concatenation operator  (+)

system.out.println("I"+"love"+"BGMI");

output of the above line is : I love BGMI

class Concatenation{

public static void main(String args[]){

System.out.println("I "+" love "+" India ");

}

}
