== operator is used to compare the references of the objects.

public boolean equals(Object o) is the method provided by the Object class. The default implementation uses ==
operator to compare two objects.

But since the method can be overridden like for String class. equals() method can be used to compare the values of two
objects.

String str1 = new String("MyName");
String str2 = new String("MyName");

if(str1 == str2){
System.out.println(“Objects are equal”)
}else{
System.out.println(“Objects are not equal”)
}

if(str1.equals(str2)){
System.out.println(“Objects are equal”)
}else{
System.out.println(“Objects are not equal”)
}

Output:
Objects are not equal
Objects are equal

Lets look at other snippet:

String str2 = "MyName";
String str3 = str2;

if(str2 == str3){
System.out.println(“Objects are equal”)
}else{
System.out.println(“Objects are not equal”)
}

if(str3.equals(str2)){
System.out.println(“Objects are equal”)
}else{
System.out.println(“Objects are not equal”)
}

Objects are equal
Objects are equal
