public class BubbleSort {

  public void sort(int[] values) {
    int numArrayLength = values.length;
    int placeholder = 0;
    for (int i = 0; i < numArrayLength; i++) {
      for (int j = 1; j < (numArrayLength - i); j++) {
        // System.out.println(i);
        // System.out.println(j);
        if (values[j - 1] > values[j]) {
          placeholder = values[j - 1];
          values[j - 1] = values[j];
          values[j] = placeholder;
        }
      }
    }
    for (int inc = 0; inc < values.length; inc++) {
      System.out.println(values[inc]);
    }
  }
