java - How do I get the first n characters of a string without checking the size or going out of bounds? -

How do I access the n characters before a string in Java without having to type? First check (inline acceptable) or IndexOutOfBoundsException ?

Here's a clean solution: 

  string upconverters = s.sstrstring (0, Math.Man (S. Long (), N)); Opinion: While this solution is "clean", I think it is actually  less readable  from a solution that uses   /  other  Clearly, if the reader has not seen this move, then  looks hard  to understand the code. IMO, code is more clear in the  if  /  else  version.

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
