Hai,

I want to fetch a character by character in a sequence from string. And i put the values into array.
for exp:
    String x = "499 afsdhjadsh";
   
    array[0] = "4";
    array[1] = "9";
    array[2] = "9";
    array[3] = " ";
             :
             :
    array[13] = "h";

         Here i fetch a character by character in a sequense from string and fix that values into the array manually. So, is there any funtions/methods to fetching a string character by character in a sequence and fix that values into array.

for exp:
       byte[] bytes = x.getBytes();
               
I think u get my point. ok, fine pls. reply ASAP          

Regards,

Friendly Arul.

char[] array = myString.toCharArray();

String str = "Woo woo" ;
char[] chars = new char[ str.length() ] ;
str.getChars( 0, str.length(), chars, 0 )  ;

If you want to turn a String into an array of String you can do the following:

String x = "499 afsdhjadsh";
String[] array = new String[x.length()];
for(int i = 0;i < array.length;i++) {
      array[0] = "" + x.charAt(i);  
}

Same end result as CEHJ's answer, but using different method:
String split[] = "499 afsdhjadsh".split(""); // unfortunately split[0] is "" - not what we want.
String array[] = new String[split.length - 1];
System.arraycopy(split, 1, array, 0, array.length);

>>String split[] = "499 afsdhjadsh".split("");

would in fact be sufficient in itself

well, as searlas says,

String split[] = "499 afsdhjadsh".split("");

will cause the first element to be an empty String.

But this solves that problem:


            String x = "499 afsdhjadsh";
            String[] array = x.split("(?<!^)");

Hmmm. Or maybe:

for ( int i = 0, iLen = x.length () ; i < iLen ; i ++ )
  array[i] = Character.toString ( x.charAt ( i ) ) ;

Might as well add one more for the complete set:
for ( int i = 0; i < array.length; i++ ) {
  array[i] = x.substring(i, i+1);
}

That one has the property that all the String elements of array share the same internal char array.

(BTW CEHJ, kudos for reading the Pattern docs and working out that negative-assertion look behind thing.  I'd have thoughtit SHOULD break on splitting "two\nlines" but it doesn't, which is nice.)
