How To Use .Equals In Java?

What does .equals do in Java?

The equals() Method example in Java

The equals() method compares two objects for equality and returns true if they are equal.

The equals() method provided in the Object class uses the identity operator (==) to determine whether two objects are equal.

For primitive data types, this gives the correct result.

What is the difference between .equals and == in Java?

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: In simple words, == checks if both objects point to the same memory location whereas . equals() evaluates to the comparison of values in the objects.

Why use .equals instead of == Java?

1) use == to compare primitive e.g. boolean, int, char etc, while use equals() to compare objects in Java. 2) == return true if two reference are of same object. Result of equals() method depends on overridden implementation. 3) For comparing String use equals() instead of == equality operator.

What is difference between == equals () and compareTo () method?

compareTo: Compares two strings lexicographically. equals: Compares this string to the specified object. compareTo compares two strings by their characters (at same index) and returns an integer (positive or negative) accordingly. equals() checks if two objects are the same or not and returns a boolean.
