Java 基础一些代码练习笔记（object-equals 方法）

public class EqualsTest{public static void main(String[] args){Student s1 = new Student("zhangsan");Student s2 = new Student("zhangsan");System.out.println(s1 == s2);System.out.println(s1.equals(s2));}}class Student{String name;public Student(String name){this.name = name;}public boolean equals(Object anObject)  //重写方法{if(this == anObject){return true;}if(anObject instanceof Student){Student student = (Student)anObject ;if(student.name.equals(this.name)){return true;}}return false;}}
