Question: What is Difference between equals method and equality operator in Java?

Answer- Both [(==) and .equals()] primary functionalities are to compare the values, but the secondary functionality is different.

(==) Operators compare the memory location while the equals() method compare the actual value of the string.

Let's Take an Example

String str1 = "CodeUno";
String str2 = "CodeUno";
String str3 = new String("CodeUno");
System.out.println(str1 == str2); // true
System.out.println(str1 == str3); // false
System.out.println(str1.equals(str3)); //true

String uses the constant pool for storing the values in the memory, both str1 and str2 are stored at the same memory location.

While for str3, heap memory is used because it uses the new operator. So its memory address will be different from str1 and str2.

That is why case 2 is false while case 3 is true because the equals method uses only value to compare strings
