Explanation:

Difference between == and .equals() method 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:

Main difference between .equals() method and == operator is that one is method and other is operator.

We can use == operators for reference comparison (address comparison) and .equals() method for content comparison. In simple words, == checks if both objects point to the same memory location whereas .equals() evaluates to the comparison of values in the objects.

If a class does not override the equals method, then by default it uses equals(Object o) method of the closest parent class that has overridden this method. See this for detail

Coding Example:

// Java program to understand

// the concept of == operator

public class Test {

public static void main(String[] args)

{

String s1 = new String("HELLO");

String s2 = new String("HELLO");

System.out.println(s1 == s2);

System.out.println(s1.equals(s2));
