java:将一个值添加到2D数组中的一列

public class AddValueTo2DArray {
    public static void main(String[] args) {
        int[][] originalArray = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
        int valueToAdd = 10;
        int columnIndexToAdd = 1;

        int[][] newArray = new int[originalArray.length][originalArray[0].length + 1];

        for (int i = 0; i < originalArray.length; i++) {
            for (int j = 0; j < originalArray[i].length + 1; j++) {
                if (j < columnIndexToAdd) {
                    newArray[i][j] = originalArray[i][j];
                } else if (j == columnIndexToAdd) {
                    newArray[i][j] = valueToAdd;
                } else {

                }
            }
        }

        // 打印新数组
        for (int i = 0; i < newArray.length; i++) {
            for (int j = 0; j < newArray[i].length; j++) {
