The Boolean logical operators are : | , & , ^ , ! , || , && , == , != . Java supplies a primitive data type called Boolean, instances of which can take the value true or false only, and have the default value false. The major use of Boolean facilities is to implement the expressions which control if decisions and while loops.

These operators act on Boolean operands according to this table

A B A|B A&B A^B !A
false false false false false true
true false true false true false
false true true false true true
true true true true false false

| the OR operator
& the AND operator
^ the XOR operator
! the NOT operator
|| the short-circuit OR operator
&& the short-circuit AND operator
== the EQUAL TO operator
!= the NOT EQUAL TO operator


Example

class Bool1{
public static void main(String args[]){

// these are boolean variables
boolean A = true;
boolean B = false;

System.out.println("A|B = "+(A|B));
System.out.println("A&B = "+(A&B));
System.out.println("!A = "+(!A));
System.out.println("A^B = "+(A^B));
System.out.println("(A|B)&A = "+((A|B)&A));
}
}
