Message:
Nested For Loops
Posted by Patti on February 15, 2002 at 12:20 AM
Hi. I'm supposed to use nested for loops to place the input integer x in the correponding column #, and at the same time have the x print in the corresponding row of the input integer y.
So x = 5, y = 3 would look like:
1234567890
1
2
3 x
4
5
6
7
8
9
0
Here's my miserable attempt. What am I missing this time? You know this textbook really stinks.
import java.io.*;
public class Graph {
public static void main(String[] args) throws IOException {
BufferedReader stdin = new BufferedReader
(new InputStreamReader(System.in));
int x;
int y;
do {
System.out.println ("Enter X (1-10, or -1 to quit):");
x = Integer.parseInt (stdin.readLine());
System.out.println ("Enter Y (1-10):");
y = Integer.parseInt (stdin.readLine());
if (x != -1){
System.out.println ("\t1234567890");
System.out.print ('\t');
for (int column = 1; column <= 10; column++)
if (x == column)
System.out.println ('X');
else
System.out.print (' '); for (int row = 1; row <= 10; row++)
if (y == row)
System.out.println ("\n1:\n2:\n3:\n4:\n5:\n6:\n7:\n8:\n9:\n0:\n");
System.out.println();
}
} while (x != -1);
}
}
