如何对给定整数数组列表值进行反金字塔？在android中

public class MainActivity extends AppCompatActivity {
    private List<Integer> integerList = Arrays.asList(1, 2, 3, 4, 5);

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        reversePyramid(integerList);
    }

    private void reversePyramid(List<Integer> integerList) {
        int size = integerList.size();

        for (int i = 0; i < size; i++) {
            // 打印空格
            for (int j = 0; j < i; j++) {
                System.out.print(" ");
            }

            // 打印整数值
            System.out.print(integerList.get(i));

            // 打印空格
            for (int k = 0; k < size - i - 1; k++) {
                System.out.print(" ");
            }

            System.out.println();
        }
    }
}
