copied!<p>Can someone please check my code and determine why my pickup function's not working.</p> <p>-- write missing methods for these procedures to occur </p> <ul> <li>Dog bob = new Dog(5);</li> <li>System.out.println(bob);</li> <li>bob.walk();</li> <li>bob.walk();</li> <li>bob.pickUp("Tennis ball");</li> <li>System.out.println(bob);</li> <li>bob.drop();</li> <li>bob.bark(); </li> <li>System.out.println(bob);</li> </ul> <p>-- In my class where I've defined the pickUp method:</p> <pre><code> public Head() { } public void pickUp(String object) { this.object = object; System.out.println("Picked up "+object); } public String getObject() { return object; } public void drop() { System.out.println("Dropped "+object); object = null; } public void bark() { System.out.println("WOOF!"); } public String toString() { return "Head is holding "+ object; } } </code></pre> <p>-- The other class where I'm utilising the method:</p> <pre><code>public class Dog { private int position; private Leg hind1; private Leg hind2; private Leg front1; private Leg front2; private Head head = new Head(); //Constructor for Dog class public Dog(int position) { hind1 = new Leg(position-2); hind2 = new Leg(position-2); front1 = new Leg(position+2); front2 = new Leg(position+2); } public void walk() { front1.step(); front2.step(); hind1.step(); hind2.step(); System.out.println("Pitter patter..."); } public String toString() { return "Head is holding " + head+", Leg at "+hind1.position+", Leg at "+ hind2.position+", Leg at "+front1.position+", Leg at "+front2.position; } public void pickup() { head.pickUp(head.object); } public void drop() { head.drop(); } public void bark() { head.bark(); } </code></pre> <p>PS. head is a new object I've made which belongs to the Head Class, Which is where the first code is from. I'm currently trying to get the second code working to display a picked up object that head picked up.</p> <p>-EDIT : Even if I do put a string in(Eg. head.pickUp("ball");), it still displays "cannot find symbol - method.pickUp(java.lang.String)" when I try running the procedures.</p>
