We override equals()method in Java to check if two objects are equal. (-Joshua Bloch) In general both equals() and “==” operator in Java are used to compare objects to check equality but here are some of the differences between the two: Main difference between .equals() method and == operator is that one is method and other is operator. In simple words, == … You must override hashCode() in every class that overrides equals(). We can use == operators for reference comparison (address comparison) and .equals() method for content comparison. Java recommends to override equals and hashCode method if equality is going to be defined by logical way or via some business logic and many classes in Java standard library does override it e.g. To compare two Java objects, we need to override both equals and hashCode (Good practice). We can override the equals method in our class to check whether two objects have same data or not. Why, you might ask, did the String class override the equals method inherited from the Object class? Two objects are considered to be equal when they are identical (contain the same data) or in other words they are in the same state. Before overriding equals()method in Java, first let's see when two objects are considered to be equal. Failure to do so will result in a violation of the general contract for Object.hashCode(), which will prevent your class from functioning properly in conjunction with all hash-based collections, including HashMap, HashSet, and Hashtable. String overrides equals, whose implementation of equals () method return true if the content of two String objects is exactly same. The Object class has some basic methods like clone (), toString (), equals (),.. etc. All classes in Java inherit from the Object class, directly or indirectly (See point 1 of this). Because the equals method Here is what the implementation of the equals method in Object looks like: public boolean equals(Object other)
