Comparative and detailed explanation of two object properties in Java

The following editor will bring you a comparison based on the properties of two objects in Java. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor and take a look.

There are two ways to compare two objects for equality:

1. Situation 1:When you only need to determine whether two objects are equal, you only need to override the equals() method. There is no need to explain here

2. Case 2:When in addition to case 1, you also need to know which attribute is different, then you need to use class reflection,

The specific code is as follows:

public static void main(String[] args) { A a = new A(); a.setUserName("a"); a.setPassword("p"); a.setQq("q"); a.setWechat("w");
