Relational Operators: Operator Meaning -------- ------- == equal to != not equal to > greater than < leass than >= greater than or equal to <= less than or equal to e.g. //logical operators in java class lo { public static void main(String ar[]) { int a, b; a=8; b=8; if(a==b) System.out.println("Value of a is equal to b"); a=0; b=8; if(a!=b) System.out.println("Value of a is not equal to b"); a=8; b=2; if(a>b) System.out.println("Value of a is big"); a=8; b=18; if(a=b) System.out.println("Value of a is greater than or equal to b"); a=5; b=8; if(a<=b) System.out.println("Value of a is less than or equal to b"); } } to compile : c:\myjavaprog>javac lo.java to run : c:\myjavaprog>java lo output: Value of a is equal to b Value of a is not equal to b Value of a is big Value of b is big Value of a is greater than or equal to b Value of a is less than or equal to b
