Trying to create a method to convert string letters into a two dimensional array

[kai13]

I'm currently stuck in my program.

I'm supposed to create a new method that inputs a message string and takes each letter and converts it into a two dimensional array of 1's and 0's. For example the letter 'H' would be

10001
10001
11111
10001
10001

My thoughts were to create a for loop and use the .charAt() method to isolate each char in the string. But from there I'm not quite sure where to go to take that char and convert it into the two dimensional array. Any suggestions?

Hi,

I know the ASCII code for the letter H is: 1001000
You can get the decimal number of H and then try to convert to binary. Here is a small program to do the conversion. You can figureout how to place this into a dimensinal array.
import java.util.*;

class ConvertString
{
public static void main (String [] args)
{
char c = 'H';
int a = c - 0;
int b = 0; intializing b to zero
Stack s = new Stack(); // declaring a new stack

System.out.println(c +" equal in decimal to: " +a);

do
{
b = (a%2); //getting the remainder
s.push(String.valueOf(b)); // push the value of b into the stack
a /= 2; // remove right most digit
} while(a != 0); //continue until all digits computed

while(!s.empty())

System.out.println(s.pop()); //result of H in binary.
}
}

Hope this helped little and good luck.
