使用Arrays.toString()输出数组的元素

Question

我已经使用下面的代码来创建和填充数组,但是,当涉及到打印数组时,我没有得到我在使用Arrays.toString()函数时所期望的结果.

而不是打印

newArray: [2, 4, 6]
newArray: [8, 10, 12]
etc..

它打印

newArray: [[I@15db9742, [I@6d06d69c, [I@7852e922, [I@4e25154f]
newArray: [[I@15db9742, [I@6d06d69c, [I@7852e922, [I@4e25154f]
etc..

代码:

public static void main(String[] args) {
    int[][] newArray = new int[4][3];
    int number = 2;
    for (int rowCounter = 0; rowCounter < newArray.length; rowCounter++) {
        for (int colCounter = 0; colCounter < newArray[rowCounter].length; colCounter++) {
            newArray[rowCounter][colCounter] = number;
            number += 2;
        }
        System.out.println("newArray: " + Arrays.toString(newArray));
    }
}

任何有关这方面的帮助将非常感激.

您可以使用deepToString而不是toString:

System.out.println(Arrays.deepToString(newArray));
