Is class equal in Java?

Java determines equality with the equals(Object o) method – two objects a and b are equal iff a. equals(b) and b. equals(a) return true . These two objects will be equal using the base Object definition of equality, so you don’t have to worry about that.

Equals() and Hashcode() in Java. The equals() and hashcode() are the two important methods provided by the Object class for comparing objects . Since the Object class is the parent class for all Java objects, hence all objects inherit the default implementation of these two methods.

Java String equals() Method Example 2

“==” or equality operator in Java is a binary operator provided by Java programming language and used to compare primitives and objects . In terms of comparing primitives like boolean, int, float “==” works fine but when it comes to comparing objects it creates confusion with the equals method in Java.

The Relational Operators OperatorDescriptionExample== (equal to)Checks if the values of two operands are equal or not, if yes then condition becomes true.(A == B) is not true.!= (not equal to)Checks if the values of two operands are equal or not, if values are not equal then condition becomes true.(A != B) is true.Java – Basic Operators – Tutorialspoint www.tutorialspoint.com › java › java_basic_operators

The equals method for class Object implements the most discriminating possible equivalence relation on objects ; that is, for any non-null reference values x and y , this method returns true if and only if x and y refer to the same object ( x == y has the value true ).
