idea创建代理方法

1.创建一个要被代理的类

package thinkinjava.reusing;

public class SpaceShipControls {
    void up(int velocity){}
    void down(int velocity){}
    void left(int velocity){}
    void right(int velocity){}
    void forward(int velocity){}
    void back(int velocity){}
    void turboBoost(){}

}

2.在类SpaceShipDelegation创建一个代理类的变量

package thinkinjava.reusing;

public class SpaceShipDelegation {
    private String name;
    private SpaceShipControls controls = new SpaceShipControls();
}

3.在SpaceShipDelegation类内，在声明变量controls分号的后面，右键鼠标选择Generate，选择：Delegate Methods
