Playing with String

[Steve Bradley]

Hi gang,

Here's one I could use some help with...

I would like to create a new String object which is the value of (char's between parameters) within an existing String object so that....

 String a = "900(10001)"
String b = "value within a's (parameter) or 10001"

I've been playing with String.toCharArray and StringBuffer objects...

What is the best route to get from String a to String b?

Have a look at the java.util.regex package.

If you don't want to mess with a StringBuffer, you can use the indexOf() and substring() methods of String. Like this:

String a = "900(10001)";
String b = a.substring(a.indexOf("(")+1,a.indexOf(")"));

substring(int,int) takes the first and last index of the string and creates a new substring of it. So if you find the indexOf() the "(" and ")" and pass those ints to substring(int,int), you'll create the proper substring. But you have to +1 to the first index so you won't include the "(".
