总结：java设计模式之----单例模式singeton

总结：没什么好说的，单例模式就是创建全局唯一的实例

//懒汉模式public class Singleton {    private  Singleton(){ }    private  static  Singleton instance = null;    public  static synchronized Singleton getInstance() {        if (instance == null){            instance = new Singleton();        }        return  instance;    }}//恶汉模式class Singleton1 {    private  Singleton1(){ }    private  static Singleton1 instance1 = new Singleton1();    public  static  Singleton1 getInstance() {        return  instance1;    }}
