java - How to use replaceFirst to Replace {....}

Question

I am having a string which contains xyaahhfhajfahj{adhadh}fsfhgs{sfsf}.

Now I want to replace {string} with a space.
I want to replace the curly brackets and the string in it with null.

I want to use replaceFirst for it but I don't know the regex for doing it.

Answer 1

Try this:

public class TestCls {
    public static void main(String[] args) {
        String str = "xyaahhfhajfahj{adhadh}fsfhgs{sfsf}";
        String str1 = str.replaceAll("\{[a-zA-z0-9]*\}", " ");// to replace string within "{" & "}" with " ".
        String str2 = str.replaceFirst("\{[a-zA-z0-9]*\}", " ");// to replace first string within "{" & "}" with " ".
        System.out.println(str1);
        System.out.println(str2);
    }
}
