[英]Java array to multi dimensional
是否可以将一个100个字符的数组转换为10 * 10的二维数组?
Here you go 干得好
char[] chars = ("01234567890123456789012345678901234567890123456789" +
"01234567890123456789012345678901234567890123456789")
.toCharArray();
char[][] char2D = new char[10][10];
for (int i = 0; i < 100; i++)
char2D[i / 10][i % 10] = chars[i];
Now the this code... 现在这段代码...
System.out.println(Arrays.deepToString(char2D).replaceAll("],","],\n"));
...prints the following ...打印以下内容
[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]]
Iterate throughout your list of 100 chars and divide it amongst the 10*10, Modulus (%) will probably be very useful. 遍历整个100个字符的列表并将其除以10 * 10,模数(%)可能非常有用。
You could use 2 nested for loops to assign the chars of the array to the appropriate element. 您可以使用2个嵌套的for循环将数组的char分配给适当的元素。
