-# Count Numbers
+# Disjoint Sets
 ## Java Solution
 
 To compile the code run
 ```java
-javac CountNumbers.java
+javac DisjointSets.java
 ```
 To run
 ```java
-java CountNumbers
+java DisjointSets
 ```
 ### Example
 ```bash
-/perlweeklychallenge-club/challenge-126/ziameraj16/java$ javac CountNumbers.java
-/perlweeklychallenge-club/challenge-126/ziameraj16/java$ java CountNumbers
-Enter the number
-15
-8
+/perlweeklychallenge-club/challenge-127/ziameraj16/java$ javac DisjointSets.java
+/perlweeklychallenge-club/challenge-127/ziameraj16/java$ java DisjointSets
+Enter comma separated list of numbers for that first set
+1,2,5,3,4
+Enter comma separate list of numbers for the second set
+4,6,7,8,9
+0
+/perlweeklychallenge-club/challenge-127/ziameraj16/java$ java DisjointSets
+Enter comma separated list of numbers for that first set
+1,3,5,7,9
+Enter comma separate list of numbers for the second set
+0,2,4,6,8
+1
