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

use substring:

class Main
{
  public static void main (String[] args) throws java.lang.Exception
  {
     String s = new String("hello world");
     System.out.println(s.substring(0, s.length()));
     System.out.println(s.substring(s.length() - 1, s.length()));
     System.out.println(s.substring(3, 4));
  }
}

or charAt:

System.out.println(s.charAt(s.length() - 1));
System.out.println(s.charAt(3));

Java is not python so negative index should be avoided to maintain constancy. However, you could make a simple conversion function.
