how do u get the last character of the last string in java?

Question

I need to get the last character of the last input string. I wrote a piece of code that gets the last letter of the first string:

public class LastCharacter { public static void main(String[] args) { String string = args[0]; System.out.println("last character: " + string.substring(string.length() -1)); } }

How can I get the last character of the last string parameter?

"i need to get the last character of the last input string" Try String string = args[args.length-1];, assuming that args.length >= 1. — Alexis C.

You may try like this:-

String str= args[args.length-1];

And to get the last character:-

char ch = str.charAt(str.length() - 1);

That should be str.length(); String has no public property called length.

@VivinPaliath:- Yes thats correct. Missed that! Updated my answer!

@VivinPaliath:- Not an issue Sir. Sometimes you do have to pay when you do miss small things just to answer it first!

(tl;dr: tl;dr.) Sorry, that was my downvote, because I had really thought that the answer missed addressing half of the question when I read it. It's now a complete answer, so either that was an artifact of voting (too) fast, or I was just tripping. Unfortunately, I can't undo my vote without a logged edit, which I hadn't realized. (Sorry--if you were to find an excuse to edit now, I'd clear the downvote.)

The last string will be at args.length - 1 in the args array, since arrays are 0-based in Java. This is also true in general for any array; the last element is always at array.length - 1.

So you can do:

String lastString = args[args.length - 1]; Character lastCharacter = lastString.charAt(lastString.length() - 1);

Int lenght = Args.length; String s = args[length -1];

Thats your last string in the input

I really can't understand the description, but based on the title, I think you want

public static void main(String[] args){ if(args != null && args.length > 0){ String lastString = args[args.length-1]; if(lastString.length() > 0){ System.out.println(lastString.charAt(lastString.length() - 1)); } } }

To get the last string:

String last = args[args.length - 1];

To get the last character:

char c = last.charAt(last.length() - 1);
