Here we can get the difference between “==” operator and “.equals()” method. the most of the interview persons expect online answer–> you can tell like this.
- “==” operator meant for “Reference Comparison/ Address Comparison
- “.equals()” method meant for Content Comparison.
Example For Reference Comparison and Content Comparison:
String s1= new String(“Interview”);
what will get the output of line 3 and 4.
- Here we have s1 and s2 are two different objects and it creates two memory locations. fig:a is the example.
- s1 points to one location and s2 points two another location then the line 3 output is false.(reference wise s1 and s2 are not Equal)
- (s1.equals(s2)) is comparing the contents of the object then the output of line 4 is true.even though object are different but content is same.(Content wise both are equal)
Note:if both objects are pointing to same memory address location then the output == is True.
