how to insert symbols

Posted: Jul 2, 2008 4:57 AM

How could I insert hyphens (-) to separate the rows and pipe symbols (|) to separate the columns in this code? I have tried a little bit but im only able to insert for the first row only.

public class Latin
{
public static void main (String[] args) {
final int N = 10;
for (int i = 1; i <= N; i++)
System.out.print(pad(i) + "|");
System.out.println();
System.out.print("---+");

for (int i = 1; i <= N; i++)
System.out.print("----");
System.out.println();

for (int i = 1; i <= N; i++) {
System.out.print(pad(i) + "|");

for (int j = 1; j <= N; j++) {
System.out.print(pad(i*j) + " ");
}
System.out.println();
}
}

public static String pad(int x) {
String s = new String();
if (x < 10) s = " " + x;
else if (x < 100) s = " " + x;
else s = "" + x;
return s;
}
}

Here is the code with comments for easy clarification.

public class LatinNumbers
{
public static void main (String[] args) {
/**
* Make table size a variable
*/
final int N = 10;
/**
* print header row
*/
System.out.print(" |");
for (int i = 1; i <= N; i++)
System.out.print(pad(i) + "|");
System.out.println();
/**
* print separator
*/
System.out.print("---+");
for (int i = 1; i <= N; i++)
System.out.print("----");
System.out.println();
/**
* print main table
*/
for (int i = 1; i <= N; i++) {
System.out.print(pad(i) + "|");
for (int j = 1; j <= N; j++) {
System.out.print(pad(i*j) + " ");
}
System.out.println();
}
} /**
* end of main class
*/

/**
* pad: add blanks to make it 3 long
*/
public static String pad(int x) {
String s = new String();
if (x < 10) s = " " + x;
else if (x < 100) s = " " + x;
else s = "" + x;
return s;
}
}

Try in this way

public class Latin {

public static void main(String [] str) {

final int N = 10;

System.out.print("------+");
for (int i = 0; i <= N; i++)
System.out.print("-----");
System.out.println("-----");

for (int i = 0; i <= N; i++) {
System.out.print(String.format("%1$5s",i)+"|");
}
System.out.println();

System.out.print("------+");
for (int i = 0; i <= N; i++)
System.out.print("-----");
System.out.println("-----");

for (int i = 1; i <= N; i++) {
System.out.print(String.format("%1$5s",pad(i)) + "|");

for (int j = 1; j <= N; j++) {
System.out.print(String.format("%1$5s",pad(i * j)) + " ");
}

System.out.println();
}

System.out.print("------+");
for (int i = 0; i <= N; i++)
System.out.print("-----");
System.out.println("-----");
}

static String pad(int x) {
String s = new String();
if (x < 10) s = " " + x;
else if (x < 100) s = " " + x;
else s = "" + x;
return s;
}
}
