Use of equals () and hashcode () for parsing Java objects   Use of equals () and hashcode () for parsing Java objects Preface   In Java, equals () and hashcode () functions work closely together. If you design one of them, you need to design

Why must I rewrite hashcode while rewriting equal?Hashcode is different integers generated by the compiler for different objects. According to the equal method, if two objects are equal (equal), the two objects must call hashcode to produce the same

2) = and equals in Java, equals in java = And equals in Java  1. If the Compare object is a value variable: only use = 2. If the Compare object is a reference variable: =: compare whether two references point to the same object instance.

Each Java object has a hashcode () and Equals () method. Many classes ignore (Override) default implementations of these methods to provide deeper semantic comparability between object instances. In the Java Philosophy and Practice section, Java
