Answer 1

package javaapplication5;
import java.util.*;
public class JavaApplication5 {
static int[][] Met(int[]arr,int row)
{
int[][] res = new int[row][arr.length];
for (int i = 0; i < row; i++) {
for (int j = 0; j < arr.length; j++) {
res[i][j] = arr[j];
}
}
for (int i = 0; i < row; i++) {
for (int j = 0; j <res[i].length; j++) {
System.out.print(res[i][j]);
if(j==arr.length-1)System.out.println();
}
}
return res;
}
public static void main(String[] args) {
int[]arr = new int[4];
for (int i = 0; i < 4; i++) {
arr[i] = i;
}
int[][]mas = Met(arr,5);
}
