1个二维数组

Question

我有2个数组，如a[3] = "1","2","3"和b[3]="1","2","3"。 将该2个数组合并为1个二维数组，如c[3][3]

c[][]
"1" "1"
"2" "2"
"3" "3"

我怎么能这样做？

Answer 1

假设您的两个数组具有相同的长度，您可以简单地遍历它们，并为c[][]构建双元素数组：

int commonLength = ... // This is the length shared by a and b
String[][] c = new String[commonLength][];
for (int i = 0 ; i != commonLength ; i++) {
    c[i] = new String[] { a[i], b[i] };
}
