Given 2 int values, return true if they are both in the range 30..40 inclusive, or they are both in the range 40..50 inclusive.

in3050(30, 31) ? true
in3050(30, 41) ? false
in3050(40, 50) ? true

public boolean in3050(int a, int b) {
if((a>=30 && a<=40)&&(b>=30 && b<=40)) return true;
else if((a>=40 && a<=50)&&(b>=40 && b<=50)) return true;
else return false;
}
