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); } }
