Java Language Primitive Data Types The boolean primitive
Example
A boolean can store one of two values, either true or false
boolean foo = true;
System.out.println("foo = " + foo); // foo = true
boolean bar = false;
System.out.println("bar = " + bar); // bar = false
boolean notFoo = !foo;
System.out.println("notFoo = " + notFoo); // notFoo = false
boolean fooAndBar = foo && bar;
System.out.println("fooAndBar = " + fooAndBar); // fooAndBar = false
boolean fooOrBar = foo || bar;
System.out.println("fooOrBar = " + fooOrBar); // fooOrBar = true
boolean fooXorBar = foo ^ bar;
System.out.println("fooXorBar = " + fooXorBar); // fooXorBar = true
The default value of a boolean is false
boolean defaultBoolean; // defaultBoolean == false
