algorithm - java - largest to smallest sort - largest is out of order -

i'm trying sorting algorithm sort largest smallest in array. here's have:

private void sort(int[] data) {     int min;     (int index = 0; index < data.length - 1; index++) {         min = index;         (int scan = index + 1; scan < data.length; scan++) {             if (data[scan] > data[min]) min = scan;             swap (data, min, index);         }     } }  private void swap(int[] data, int pos0, int pos1) {     int temp = data[pos0];     data[pos0] = data[pos1];     data[pos1] = temp; } 

the output is:

3 3 4 2 2 2 2 1 1 1 1 1 1 

why second largest number out of order?

i keep going through , i'm missing something.

you closing if statement earlier

 if (data[scan] > data[min]) min = scan;             swap (data, min, index); 

swap() invoked regard less of if condition
