Java的Object类讲解案例代码 equals()、hashCode()、finalize()、clone()、wait()

package com.xiaoshan.demo1; import java.util.Objects; public class Person implements Cloneable { // 姓名 private String name; // 年龄 private int age; // 兴趣爱好 private Interest interest; public Person(String name, int age) { this.name = name; this.age = age; } public Person(String name, int age, Interest interest) { this.name = name; this.age = age; this.interest = interest; } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; Person person = (Person) o; return age == person.age && Objects.equals(name, person.name) && Objects.equals(interest, person.interest); } @Override public int hashCode() { return Objects.hash(name, age, interest); } // Getter and Setter methods public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public Interest getInterest() { return interest; } public void setInterest(Interest interest) { this.interest = interest; } @Override public String toString() { return "Person{" + "name='" + name + '\'' + ", age=" + age + ", interest=" + interest + '}'; } @Override public void finalize() { // 释放占用的资源或执行清理操作的代码 System.out.println("正在执行finalize()方法"); } @Override public Object clone() throws CloneNotSupportedException { return super.clone(); } }
