面向对象 哈希码 getclass toString 的用法，getclasstostring

package com.java;

public class object20 {

    public static void main(String[] args) {
        Object o=new Object();
        int hashCode1 = o.hashCode();
        int hashCode2 = o.hashCode();
        System.out.println(hashCode1);
        System.out.println(hashCode2);
        Object o1=new Object();
        int hashCode3 = o1.hashCode();
        int hashCode4 = o1.hashCode();
        System.out.println(hashCode3);
        System.out.println(hashCode4);
         Class c = o1.getClass();
         System.out.println(c.getName());
         String string = o1.toString();
         System.out.println(string);
    String string2=o1.getClass().getName()+"@"+Integer.toHexString(o1.hashCode());
    }
