java如何實作數組排序

public class TestDemo {
    public static void bubbleSort(int[] array){
        for (int i = 0; i <array.length-1 ; i++) {
            boolean flg = false;
            for (int j = 0; j <array.length-1-i ; j++) {
                if(array[j]>array[j+1]){
                    int tmp = array[j];
                    array[j] = array[j+1];
                    array[j+1]= tmp;
                    flg = true;
                }
            }
            if(flg = false){
                return;
            }
 
        }
    }
    public static void main(String[] args) {
        int[] array = {12,1,23,15,16,13,17};
        bubbleSort(array);
        System.out.println(Arrays.toString(array));
 
 
    }
}
