就像上面这样,但在Java eclipse的控制台中,没有花哨的按钮和GUI,但在控制台中,这就是我所拥有的....
import java.util.Scanner;
public class Client {
public static void main(String[] args){
Scanner input = new Scanner(System.in);
int[][] table = new int[4][4];
for (int i=0; i < table.length; i++) {
for (int j=0; j < table.length; j++) {
System.out.println("Enter a number.");
int x = input.nextInt();
table[i][j] = x;
System.out.print(table[i][j] + " ");
}
System.out.println();
}
System.out.println(table);
}
}

当我输入所有内容并且控制台终止时,这就是我得到的:
Enter a number.
1
1 Enter a number.
1
1 Enter a number.
1
1 Enter a number.
1

考虑使用java.util.Arrays.
那里有一种叫做的方法deepToString.这将在这里工作得很好.
System.out.println(Arrays.deepToString(table));

您需要将数组与输入数字分开打印。所以你可以这样做:
public class PrintArray {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int[][] table = new int[4][4];
for (int i = 0; i < table.length; i++) {
for (int j = 0; j < table.length; j++) {
// System.out.println("Enter a number.");
int x = input.nextInt();
table[i][j] = x;
}
//System.out.println();
}
// System.out.println(table);
for (int i = 0; i < table.length; i++) {
for (int j = 0; j < table[i].length; j++) {
System.out.print(table[i][j] + " ");
}
System.out.println();
}
}
}
