java - Why does if statement not work properly inside for loop? -

i have array classified same value..

int[] clusters= 0    1    2    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    2    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1    1 int[] clusterdistinct = 0 1 2 

it fine using code below, on last statement (if statement) inside loop not print. don't know whats wrong code

private void autoclustering(int[] clusters) {     int[] clusterdistinct = getclusters(clusters);      (int = 0; < clusterdistinct.length; i++) {         system.out.println("\ncluster " + clusterdistinct[i]);         (int j = 0; j < clusters.length; j++) {             if (clusters[j] == clusterdistinct[i]){                 system.out.print(j+",");             }         }     } }  private int[] getclusters(int[] clusters) {         arraylist<integer> klaster = new arraylist<integer>();         (int = 0; < clusters.length; i++) {             boolean isdistinct = false;             (int j = 0; j < i; j++) {                 if (clusters[i] == clusters[j]) {                     isdistinct = true;                     break;                 }             }             if (!isdistinct) {                 klaster.add(clusters[i]);             }         }          int[] clusterdistinct = new int[klaster.size()];         (int = 0; < clusterdistinct.length; i++)             clusterdistinct[i] = klaster.get(i).intvalue();         return clusterdistinct;     } 

here output.. if statement not working (not print) on last cluster. cluster 2 (last statement) not print, should print 2,25 why not print anything?

print newline character \n after loop flush output buffer.
