JavaOOP 单例模式

package cn.hello.test6单例;class Singineton{ //这是一个普通类 //这是 饿汉模式// private static final Singineton  inSingineton=new Singineton(); private static  Singineton  inSingineton;public static Singineton getInSingineton() {if (inSingineton==null) {inSingineton=new Singineton(); //这是懒汉模式}return inSingineton;    }//public static void setInSingineton(Singineton inSingineton) {//Singineton.inSingineton = inSingineton;//}private Singineton() {  //构造方法}public void print(){System.out.println("这是单例");} }public class Test {public static void main(String[] args) {  Singineton inst=null;  //声明对象  inst=Singineton.getInSingineton();  inst.print();}}
