using Math.random() to generate only even and odd numbers in a certain interval

The problem says to

Write a method that takes a Rectangle as a parameter, sets i开发者_如何学JAVAts length to a random, even integer between 10 and 20 inclusive, and sets its width to a random, odd integer greater than or equal to 7 and less than 14. Use Math.random() to generate random numbers.

This method must be called randomize() and it must take a Rectangle parameter.

You can call your method in the program's main method so you can test whether it works, but you must remove or comment out the main method before checking your code for a score. You will also need to make sure you do not remove the import statement import testing.Math as this is required to check your code for a score.

So far I have

import java.util.Scanner;
import shapes.*;
import testing.Math;

public class U5_L3_Activity_Two{

  public static void randomize(Rectangle p) {
    int len = (int)(Math.random() * 10);
    if (len < 5) {
      len += 5;
    }
    double length = (len * 2);
    
    int wid = (int)(Math.random() * 10);
    if (wid < 4) {
      wid += 9;
    }
    if (wid == 7) {
      wid = 6;
    }
    double width = (wid * 2) + 1;
  
    p.setWidth(width);
    p.setLength(length);
  }
}

I can't pass the test cases.

This test case checks that your randomize method randomly changes the length of the Rectangle parameter to an even number.

and

This test case checks that your randomize method randomly changes the width of the Rectangle parameter to an odd number.

So I'm pretty sure it just means I'm not correctly making my program even and odd.
