Question

怎么知道某个元素在二维数组里的“位置”

Answer 1

public class $ {
public static void main(String[] args) {

int[][] arr = { { 1, 2, 3 }, { 4, 5, 6 }, { 6, 7, 8 } };

find(arr, 4);
find(arr, 6);
}

private static void find(int[][] arr, int num) {

for (int i = 0; i < arr.length; i++) {
int[] tmp = arr[i];
for (int j = 0; j < tmp.length; j++) {

if (arr[i][j] == num) {
System.out.println(num + "的位置是:(" + i + "," + j + ")");
}
}
}
}
}
