Class to another

Question

Hi ca anybody help?
I've just started learning java and I'm stuck. I'm doing an OU course and created 2 objects, one simulates a frog and the other invokes a random number (RandomNumberGenerator). So how do I get the frog object to use a method from the other object? I want to move the frog randomly, using the method of the RandomNumberGenerator.

Hi and thanks,
Here is the code of the randomNumberGenerator:
public class RandomNumberGenerator
* This will generate a random number between 1 and 5.
     public int between1And5()
     return ((new Random()).nextInt(5) + 1);
Which as you know, thiswould give a random number between 1 and 5.
Which I want to use as part of the argument in the method of the Frog class, here is the code:
public class RandomFrog extends Frog
     * Constructor for objects of class RandomFrog
     public RandomFrog()
     super();
     * If the argument newPosition lies between 1 and 11 inclusive
     * the position of the receiver is set to the argument.
     * Otherwise position is set to 5.
     public void setPosition(int newPosition)
     if ((newPosition > 1 ) && (newPosition < 11 ))
super.setPosition(newPosition);
else
super.setPosition(5);
* Increments the position of the receiver, by the random
* number (between 1 and 5 inclusive).
public void randomLeft()
super.setPosition(getPosition() - Here is where I need to use the other class method);
Hope this is a bit clearer?
Jon.
