value is equal (the hash property value and entry key after the hash method conversion of the hash value is equal). The above situation can be summed up as: HashMap to determine whether the key exists in the HASHMAP has two requirements 1. Key value is equal; 2. Whether the hashcode is equal; So when we define a class, if the Equals () method is overridden, but hashcode does not guarantee equality, it causes the problem of HashMap "work exception" to occur when the class instance is used as a k
