Boolean operators
What will be the output of the following method with various values of a and b?
public void output(boolean a, boolean b) {
    if (a) {
        System.out.println("A");
    } else if (a && b) {
        System.out.println("A && B");
    } else {
        if (!b) {
            System.out.println("notB");
        } else {
            System.out.println("ELSE");
        }
    }
}

A. If a is true and b is true, then the output is "A && B"
B. If a is true and b is false, then the output is "notB"
C. If a is false and b is true, then the output is "ELSE"
D. If a is false and b is false, then the output is "ELSE"

option C

the first if n else if fails bcoz a is false..and then inside else the first if fails bcoz (~true=false) and hence goes to inner else and prints ELSE
