Java-如何访问另一个类的ArrayList？

import java.util.ArrayList;public class numbers {   private int number1 = 50;   private int number2 = 100;   private List<Integer> list;   public numbers() {       list = new ArrayList<Integer>();       list.add(number1);       list.add(number2);   }   public List<Integer> getList() {       return list;   }}

和测试类：

import java.util.ArrayList;public class test {   private numbers number;   //example   public test() {     number = new numbers();     List<Integer> list = number.getList();     //hurray !   }}
