How do Booleans work?

either true or false. declare variable and set as either true or false. bool onTime; onTime = true;

boolean have only two values either true or false...u can try by using operators int a=34; int b=16; boolean k=(a>15 && b <40); System.out.println(k); This prints true.. hope this helps

can i declare a boolean variable with the T or F value (this letters equivalent to True or False)?

a boolean is 0 or 1. It's like a licht switch on and off.

boolean return positive or negative values which is compiled by Java and it will return true if positive else false negative..
