How to retrieve specific values from String

Question

I am working on something that enforces me to clean a String value by retrieving only some specific substring values.

The String follows the following pattern:

param1=value1&param2=value2&param3=value3&param4=value4&param5=value5

I need a solution that retrieves the appropriate values {value1, value2, value3}.

Is there anything ready for this purpose in commans-lang3?

You could split the string on & and = and then process the bits however you want — Robin Topper, Apr 20 '17 at 08:18

To add on to Robin, once you finish splitting, call them by their index — OtherClare, Apr 20 '17 at 08:20

As suggested in the comments, you may split on & then on = , like this example :

String testString = "param1=value1&param2=value2&param3=value3&param4=value4&param5=value5";

String[] paramValues = testString.split("\\&");

for (String paramValue : paramValues) {

    System.out.println(paramValue.split("\\=")[1]);
}
