Java Coding Problems

45. Checking the subrange in the range from 0 to length

Let's follow the same flow from the previous problem. So, this time, the Function class will look as follows:

public class Function {  private final int n;  public Function(int n) {    this.n = n;  }  public int yMinusX(int x, int y) {    return y - x;  }}

Notice that the preceding snippet of code doesn't assume any range restrictions over x, y, and n. Now, let's impose the following ranges:

• n must be between 0 (inclusive) and 101 (exclusive), so n belongs to [0, 101].
• In the yMinusX() method, the range bounded by x and y, [x, y] must be a subrange of [0, n].

These ranges can be imposed in code via the if statements as follows:

public class Function { private static final int N_UPPER_BOUND = ...
