Program to demonstrate the relational operator '==' (i.e.Equal to) 
class OperatorEqualTo { public static void main(String args[]) { int a=3,b=3; System.out.println(a==b); //a==b will return 'true' as 3==3 is true } }
Output of this program:
true

Program to demonstrate the relational operator '!=' (i.e.Not Equal to) 
class OperatorNotEqualTo { public static void main(String args[]) { int a=3,b=3; System.out.println(a!=b); //a!=b will return 'false' as 3!=3 is false } }
Output of this program:
false

Program to demonstrate the relational operator '<' (i.e. less than) 
class OperatorLessThan { public static void main(String args[]) { int a=3,b=4,c=6; System.out.print(" a is less than b is "); System.out.println(a<b); System.out.print(" c is less than b is "); System.out.println(c<b); } } Output of this program: a is less than b is true c is less than b is false 
Program to demonstrate the relational operator '>' (i.e. greater than) 
class OperatorGreaterThan { public static void main(String args[]) { int a=3,b=4,c=6; System.out.print(" a is greater than b is "); System.out.println(a>b); System.out.print(" c is greater than b is "); System.out.println(c>b); } } Output of this program: a is greater than b is false c is greater than b is true 
Program to demonstrate the relational operator '<=' (i.e.less than or Equal to) 
class OperatorLessThanOrEqualTo { public static void main(String args[]) { int a=3,b=3,c=6; System.out.print(" a is less than or equal to b is "); System.out.println(a<=b); //a and b are equal hence a<=b will return true System.out.print(" a is less than or equal to c is "); System.out.println(a<=c); // a is less than c hence a<=c will return true System.out.print(" c is less than or equal to b is "); System.out.println(c<=b); // c is neither less than b nor equal to b hence c<=b will return false } } Output of this program: a is less than or equal to b is true a is less than or equal to c is true c is less than or equal to b is false 
Program to demonstrate the relational operator '>=' (i.e. greater than or Equal to) 
class OperatorLessThanOrEqualTo { public static void main(String args[]) { int a=3,b=3,c=6; System.out.print(" a is less than or equal to b is "); System.out.println(a>=b); //a and b are equal hence a>=b will return true System.out.print(" a is less than or equal to c is "); System.out.println(a>=c); // a is neither greater than c nor equal to c hence a>=c will return false System.out.print(" c is less than or equal to b is "); System.out.println(c>=b); // c is greater than b hence c>=b will return true } } Output of this program: a is greater than or equal to b is true a is greater than or equal to c is false c is greater than or equal to b is true

Hi Arun, This is Suresh KSV
In S.O.P statement message and output message is different.Please change that in Program to demonstrate the relational operator '>=' (i.e. greater than or Equal to).
System.out.print(" a is less than or equal to b is ");
System.out.println(a>=b); //a and b are equal hence a>=b will return true
System.out.print(" a is less than or equal to c is ");
System.out.println(a>=c); // a is neither greater than c nor equal to c hence a>=c will return false
System.out.print(" c is less than or equal to b is ");
System.out.println(c>=b);
But Output is
a is greater than or equal to b is true
a is greater than or equal to c is false
c is greater than or equal to b is true
