Question

/* Given three ints, a b c, return true if one of them is 10 or more less

* than one of the others.
*/
public boolean lessBy10(int a, int b, int c) Math.abs(a - c) >= 10

Answer 1

The question is about implementing a Java method that returns true if the difference between any two of the given three integers is at least 10. The method uses the Math.abs function to compute absolute differences and logical OR to return the right boolean value.

Step-by-step explanation:

The student's question pertains to a programming exercise, specifically one that involves writing a Java method. The method named lessBy10 should return a boolean value, the result of which determines if one of the three provided integers (a, b, or c) is at least 10 less than one of the others. This problem is solved by using the Math.abs function in Java to calculate the absolute value of the difference between each pair of numbers, and then checking to see if that difference is 10 or greater using the logical OR operator (||).

The provided implementation is correct and efficient, utilizing short-circuit evaluation to only compute the necessary comparisons until it finds one that meets the criteria. If the difference between a and b, a and c, or b and c is 10 or more, the method will return true; otherwise, it will return false.
