Is there a Java equivalent to Python's Easy String Splicing?

Question

Ok, what I want to know is is there a way with Java to do what Python can do below...

string_sample = \"hello world\"

string_sample[:-1]
>>> \"hell         


        

Answer 1

I think there is no such Java string library providing exactly the same thing provided by python. Probably the best you can do is to build a new class which provides the functions you need. Since the String in java is a final class which you cannot have a class extend from it, you need to use composition. For example:

public class PythonString {
  protected String value;
  public PythonString(String str) {
    value = new String(str);
  }

  public char charAt(int index) {
    if (index < 0) {
      return value.charAt(value.length() + index);
    }
    return value.charAt(index);
  }

  ....

}

Another alternative is to create a static string library.
