Catching Game. Needs minor adjustments

Hey guys! I need help. I'm making a catching game in Greenfoot ver. 3.1.0. It went fine, which surprised me because I am a beginner and don't know anything else much but the basics. However, my basket keeps going off the screen. This is the code of basket:

import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)

/**
 * Write a description of class cb here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 */
public class cb extends Actor
{
    /**
     * Act - do whatever the cb wants to do. This method is called whenever
     * the 'Act' or 'Run' button gets pressed in the environment.
     */
    public void act() 
    {
        checkKeys();
        AppleCrunch();
    }
    public void AppleCrunch()
    {
        if(isTouching(apple.class))
        {
            getOneObjectAtOffset(0,0,apple.class);
            ((counter2)getWorld().getObjects(counter2.class).get(0)).bumpCount(15);
        }
        if(isTouching(banana.class))
        {
            getOneObjectAtOffset(0,0,banana.class);
            ((counter2)getWorld().getObjects(counter2.class).get(0)).bumpCount(8);
        }
        if(isTouching(cherry.class))
        {
            getOneObjectAtOffset(0,0,cherry.class);
            ((counter2)getWorld().getObjects(counter2.class).get(0)).bumpCount(5);
        }
        if(isTouching(grape.class))
        {
            getOneObjectAtOffset(0,0,grape.class);
            ((counter2)getWorld().getObjects(counter2.class).get(0)).bumpCount(20);
        }
    }
    public void checkKeys()
    {
        if(Greenfoot.isKeyDown("left"))
        {
            move(-10);
        }
        if(Greenfoot.isKeyDown("right"))
        {
            move(10);
        }
    }
}

Also, I want the fruits and bomb to fall slower and more random. Which in these ff. codes should I change? code of world (park1):

import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)

/**

    /**
     * Constructor for objects of class park1.
     * 
     */
    public park1()   
    {
       super(600, 400, 1);
       AppleCrunch();
       prepare();
       BananaSplit();

        score.setLocation(59,44);
        cb.setLocation(373,403);
    }
    public void AppleCrunch()
    {
        if(Greenfoot.getRandomNumber(2)<50)
        {
            addObject(new apple(),Greenfoot.getRandomNumber(519),20);
        }
    }

        }
    }

    {
        if(Greenfoot.getRandomNumber(2)<50)
        {
            addObject(new cherry(),Greenfoot.getRandomNumber(519),20);
        }
    }
    public void Kaboom()
    {
        if(Greenfoot.getRandomNumber(2)<50)

This is all. Please help me and state what is wrong specifically because like I said, I am just a beginner and don't know much yet. I need help as soon as possible. THANK YOU FOR ALL THOSE WHO WILL HELP ME!!! =.=

It also seems to be in instant win because I only caught one fruit and it is already in 100+ score. How do I change this?

getOneObjectAtOffset(0,0,apple.class);

A line like this is not doing anything. You should remove the fruit when the cb collects it or you will keep generating points as long as it is touching the fruit. The fruit itself should not check if it is touching the cb, it is enough when the code is in one class. Moving 10 each act cycle (cb and fruits) also seems a bit fast but maybe this is wanted.

if(Greenfoot.getRandomNumber(2)<50)

getRandomNumber(2) returns either 0 or 1 randomly, so it will always be below 50 and spawn a new fruit whenever the one was collected.

Ohhhhh...... Ok, I get it. Thanks Super_Hippo.

Okay. I have the right score, but how about the others that cb did not touch? How will they go back to the top?

I thought they would just be removed from the world and the world adds a new one because it sees that none is in the world. Maybe decreasing score if the user failed to catch it.
