Multiple replace in one statement

test = test.replace("COOL", "");
        test = test.replace(" ", "");
        test = test.replace("GRUPPE=", "");
        test = test.replace("\n", "");
        test = test.replace("\r", "");

This is only an example. There are 20 more Strings which I want to replace.

And now I want to get this in only one statement. Is there any possibility of doing this? Or is the code the "best" for doing this?

I develop for JAVA.

Try below code.

     var array = new string[] { "COOL", "gruppe", "\n" };
     string test = "COOL gruppe test";
    foreach(var result in array)
    {
          test = test.Replace(result, "");
    }

If you are going to replace all instances of those words, you can do it like this

test.replaceAll("COOL|\\s+|GRUPPE", "");

\\s+ is taken by regex as \s+ which includes white spaces and new line characters.

you can use regular expressions for that.

so you will need something like:

rest.replaceAll("(COOL|\s|GRUPPE=|\n|\r)", "")

in regex you join different variants with | symbol which means OR.
