How to strip off piece of text from a string

Question

I have the following String text:

/Return/ReturnData/IRS1040/DependentWorksheetPP[1]/DependentCodePP

I'd like to strip off the [1] index so I just have:

/Return/ReturnData/IRS1040/DependentWorksheetPP/DependentCodePP

How can I accomplish this in Java?

string.replaceAll("[?]","");

This doesn't seem to work.

Any help or info would be much appreciated

Strings are immutable in Java, 'replaceAll' will return a new string that has the replacements. See String.replaceAll. Possible duplicate: stackoverflow.com/questions/10951333/…. Is this the issue you're having? — Xiao

First, in Java, String is immutable (so be sure to assign the result of replaceAll). Next, the [ and ] are meaningful in a regular expression (escape them). And \\d+ is one or more digit. Something like,

String str = "/Return/ReturnData/IRS1040/DependentWorksheetPP[1]/" + "DependentCodePP"; str = str.replaceAll("\\[\\d+\\]", ""); System.out.println(str);

Output is

/Return/ReturnData/IRS1040/DependentWorksheetPP/DependentCodePP

string.replaceAll("\\[.*?\\]","");

You need to escape [] as they are special characters in regex.
