Java（课后练习：求二维数组的最值及其位置）

• 代码

package s02;


public class Task04_2 {
    public static void main(String[] args) {
        int m = (int)(Math.random()*10)+1;
        int n = (int)(Math.random()*10)+1;
        int [][] a = new int[m][n];
        int maxn = a[0][0];
        int fi = 0, fj = 0;
        for (int i = 0; i < a.length; i++) {
            for (int j = 0; j < a[i].length; j++) {
                a[i][j] = (int)(Math.random()*100);
                if (a[i][j] > maxn) {
                    maxn = a[i][j];
                    fi = i;
                    fj = j;
                }
            }
        }
        System.out.println("二维数组为：");
        for (int[] i:a) {
            for (int j:i) {
                System.out.print(j + "t");
            }
            System.out.println();
        }
        System.out.println("最大值：" + maxn);
        System.out.println("位置是：[" + (fi + 1) + "," + (fj + 1) + "]");
    }
}
