Find Unique Number in Arrays in Java   public class Practice { public static void uniqueFun ( int [] arr){ // Arrays.sort(arr); for ( int i= 0 ; i<arr. length ; i++){ int cnt= 0 ; for ( int j= 0 ; j<arr. length ; j++) { if (arr[i] == arr[j]) { cnt++ ; } } if (cnt== 1 ){ System. out .println(arr[i]) ; } } } public static void main (String[] args) { int [] ar = { 4 , 4 , 5 , 5 , 6 , 7 , 7 , 7 , 4 , 5 , 2 , 2 , 2 } ; uniqueFun (ar) ; } }
