How to split a delimited string into its elements

[Angus]

Hello

I have a semi-colon delimited string eg apple;pear;banana;pineapple; and
want to extract each 'element' of the string. All I really want to do is
print each individual element. But when I get the code working I want to
use in a Java applet so only want to use up to Java 1.1

How would I achieve this?

If you don't have to worry about escape characters or special treatment of
semi-colons within quotes, just use StringTokenizer. Search on Google
Groups for last week's thread about parsing CSV files for more complete
solutions.

Try using String split(). The last I heard Sun was trying to move away
from StringTokenizer to this string function. Example:

String target = "apple;pear;banana;pineapple;";
String[] data = target.split(";");
for (String item : data)
System.out.println(item );

Except, the OP specifically said Java 1.1, and split is relatively
knew.
Having said that, there is usually no good reason to stay with Java 1.1
these days, he should indeed use split for the simple case.

origString.split(";");

Here's a function I used in a 1.1 applet once...

/**Splits a string into a list of strings
* @param - source, String original string to be split
* @param - splitAt, token to split at
* @return - Returns a String array containing the sub elements
*/
protected String[] split(String source, String splitAt)
{
int cElements = 0;
for (int i = 0; i < source.length(); i++)
{
if(source.charAt(i) == splitAt.charAt(0))
cElements+=1;
}
String tmpResult[] = new String[cElements+1];

int prevIndex = 0;
for(int i = 0; i <= cElements; i++)
{
int curIndex = source.indexOf(splitAt,prevIndex+1);
if(curIndex == -1)
curIndex = source.length();

tmpResult = new String(source.substring(prevIndex !=0 ? prevIndex+1
: prevIndex , curIndex));
prevIndex = curIndex;
}

return tmpResult;
}
....

String target = "apple;pear;banana;pineapple;";
String[] data = target.split(target,";");
for (int i=0; i<data.length; i++)
System.out.println(data);

Oops...

That should read:

String[] data = split(target,";");
