Here's my version:

import java.util.Random;

public class MyRandom
final static Random random = new Random();

static int getTargetNumberToGuess()
return random.nextInt(100) + 1;

The main differences are:

  1. The Random object is static, since you really only need to create it once and use it many times in your program, instead of creating one every time you want a new random number.
  2. It has a more descriptive name, which becomes even more important when it is a class or instance variable.
  3. To get the range of 1 to 100, you need to call nextInt() with the parameter of 100 (which will give a random number from 0 to 99) and then add 1 to it.

> What I suggest is for you to use the java.util.Random class for Random number generation. The code below might help you....

> import java.util.Random;
> public class MyRandom {

> public MyRandom() {
> }
> public static void main(String args[])
> {
> Random x = new Random();
> System.out.println(x.nextInt(101));

> }
> }
