Java如何以编程方式初始化2d对象数组？

我想像这样初始化2d数组。 我这样做太愚蠢了。 如何使用循环来执行此操作？

---

我试着把它放在循环中。但是{}似乎只能在声明时使用

你可以用一个复合物

作为循环
，类似于

Object[][] dataEntriesg = {
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
};

dataEntriesg=新对象[25][5]；
for（int row=0；row

…例如，
您可以将复合
用于循环
，类似于

Object[][] dataEntriesg = {
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},
        {"","","","",""},

        {"","","","",""},

        {"","","","",""},
        {"","","","",""},

…例如
将我的样本用作蓝图

例如，假设
x=newint[3][4]
，
x[0]
，
x[1]
和
x[2]
是一维的
数组和每个数组包含四个元素，如图所示。length
为
3
，和
x[0]。长度
，
x[1]。长度
和
x[2]。长度
是
4


如何遍历和初始化2D阵列您可以遵循以下示例作为您的蓝图：

dataEntriesg = new Object[25][5];
for (int row = 0; row < dataEntriesg.length; row++) {
    for (int col = 0; col < dataEntriesg[row].length; col++) {
        dataEntriesg[row][col] = "";
    }
}

您可以使用单个循环，但我认为您会发现循环的复合

更容易（两个循环，一个循环在另一个循环中…）顺便问一下，为什么是对象？这些是字符串…@m0skit0因为我需要将其传入一个函数requires object[]type@BufBills那你为什么要创建字符串数组呢？你可以使用一个循环，但我想你会发现一个复合的
for循环
