Question

Problem 16)(Java) Write a complete definition for a public static method
called closeEnough that takes a double and an integer and returns true
if the double is within one unit of the integer. For example

      closeEnough(3.9, 5)  ->  false
      closeEnough(4.1, 5)  ->  true
      closeEnough(6.0, 5)  ->  true

Answer 1

public static boolean closeEnough(double d, int i){
    if(Math.abs(d-i)<=1){
        return true;
    }
    else{
        return false;
    }
}
