-# Disjoint Sets
+# Odd Number
 ## Java Solution
 
 To compile the code run
 ```java
-javac DisjointSets.java
+javac OddNumber.java
 ```
 To run
 ```java
-java DisjointSets
+java OddNumber
 ```
 ### Example
 ```bash
-/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
