创建之单列模式设计模式测试

package singleton;

public class Singleton {
    String name;
    static Singleton singleton = new Singleton();
    
    private Singleton(){}  //私有化，禁止类外面创建的对象实例化成员变量
    
    public static Singleton getInstance(){  
        return singleton;  
    }  
    
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Singleton A=Singleton.getInstance();//Singleton A=singleton;
        A.name="小妞";
        
        System.out.println(singleton.name);
        
        Singleton B=Singleton.getInstance();
        System.out.print(B.name);
    }
