-# Largest Multiple
+# Sum of Squares
 ## Java Solution
 
 To compile the code run
 ```java
-javac LargestMultiple.java
+javac SumOfSquares.java
 ```
 To run
 ```java
-java LargestMultiple
+java SumOfSquares
 ```
 ### Example
 ```bash
-/perlweeklychallenge-club/challenge-115/ziameraj16/java$ javac LargestMultiple.java
-/perlweeklychallenge-club/challenge-115/ziameraj16/java$ java LargestMultiple
-Enter comma separate numbers
-1,0,2,6
-Output: 6210
-/perlweeklychallenge-club/challenge-115/ziameraj16/java$ java LargestMultiple
-Enter comma separate numbers
-1,4,2,8
-Output: 8412
-/perlweeklychallenge-club/challenge-115/ziameraj16/java$ java LargestMultiple
-Enter comma separate numbers
-4,1,7,6
-Output: 7614
+/perlweeklychallenge-club/challenge-116/ziameraj16/java$ javac SumOfSquares.java
