Extract Digits from a String

[stdq]

Hi, everyone. So, suppose I have a String variable called str, with the value "123". I also have an array of integers, with length 3. I am trying to put each digit in the array:

 
public class test
{
    public static void main( String[] args )
    {
        int digits[] = new int[ 3 ];
        String str = "123";
 
        /* 'Extract' digits: */
        for ( int i = str.length() - 1 ; i >= 0 ; i-- )
        {
            digits[ i ] = ( int ) str.charAt( i );
        }
 
        /* Print array: */
        for ( int i = 0 ; i <= 2 ; i++ )
        {
            System.out.print( digits[ i ] );
        }
    }
}
 
 

This isn't working, though. IfWhen I print the number, the value 495051 is displayed. What am I doing wrong?

Solved it by changing line 12 to

digits[ i ] = Character.getNumericValue( str.charAt( i ) );

I think I was working with the ASCII and/or Unicode representations of 1, 2 and 3 instead.
