插入排序Java未正确排序

我正在尝试自己编写冒泡排序、选择排序和插入排序的程序。但是，我在插入排序方面遇到了问题。我将提供我的代码以及每行代码的作用

public void sortMethod() {
    int count = 1;
    for (int j = 0; j < Unsorted.length - 1; j++) {
        int index = 0;
        if (Unsorted[count] < Unsorted[count - 1]) {
            int temp = Unsorted[count];
            for (int i = count; i > 0; i--) {
                if (Unsorted[i] > Unsorted[count]) {
                    index = i;
                    Unsorted[i] = Unsorted[i - 1];
                }
            }
            Unsorted[index] = Unsorted[count];
        }
        count = count + 1;
    }
}

这是我修改代码以使其执行插入排序所需的最小数量，因为我知道这样的排序是有效的。请注意，您使用的整数值比需要的要多，如果不需要的话，还有一个额外的

。我添加了大量注释以反映我在修复代码时的想法，因此希望您能够理解代码的作用：

public class Test
    private static int[] Unsorted = {444, 7, 22, 4, 3, 2, 1, -34, -999};

    public static void sortMethod() {

        // We'll consider each position in the array in order.  For each round,
        // 'j' is pointing at the last item in the part of the array that we know is
        // correctly sorted.  The first item after 'j' is the next candidate.  We
        // want to INSERT it into the right place in the part of the array that
        // is already sorted. NOTE: The first item is never a candidate because
        // an array with one element is always sorted.
        for (int j = 0; j < Unsorted.length - 1; j++) {
            // save off next candidate value, the first value that may be out of order
            int temp = Unsorted[j + 1];

            // Move all the items in the sorted part of the array that are greater
            // than the candidate up one spot.  We know we have room to shift up
            // because we've saved off the value at the candiate position.
            int i = j;
            while (i >= 0 && Unsorted[i] > temp) {
                Unsorted[i + 1] = Unsorted[i];
                i = i - 1;
            }
            // Put the candidate in the hole that is left.  This inserts it such
            // that everything below it has a value smaller than it, and everything
            // above it has a value greater than it.
            Unsorted[i + 1] = temp;

            // Now the array is sorted up to  the position j is pointing to and one
            // beyond, so we'll advance j by one position for the next round
        }
    }

    public static void main(String[] args) {
        sortMethod();
        for (int i = 0 ; i < Unsorted.length ; i++)
