Accessing arrays with methods

Question

Hi guys i\'m just starting to learn Java, and I wondering how can I access an array that was declared in a method from another method? The design look like this:

Answer 1

You need to move your declaration to make it a member, otherwise it will go out of scope once the initializeArray call ends. Then you can access the array from both methods. Try this:

public class Arrays{
   float[] array;
   int arraysize = 2;

   public void initializeArray(){
      array = new float[arraySize];   // Declare array  
   }

   public void accessArray(){
      array[0] = 1.0f;
   }
 }
