Tip: Understanding the Unary Operator in Java

Java uses the symbol tilde (~) to represent the operator. The following examples are clearly illustrative of the use and outcome of this operator.

Code sample:

public class JavaUnary
{
public static void main(String args[])
{
JavaUnary javaUnary = new JavaUnary();
javaUnary.proceed();
}

private void proceed()
{
System.out.println("Unary (~) of 55: " + ~ 55 ); //Output is 1 number lesser than the negative of the argument
System.out.println("Unary (~) of -55: " + ~ -55 ); //Output is 1 number lesser than the positive of the argument
}
}
/*

Expected output:

[root@mypc]# java JavaUnary
Unary (~) of 55: -56
Unary (~) of -55: 54
*/
