ArrayIndexOutOfBoundsException 14 Years Ago by NT. Hi, I am trying to divide array elements in low and high using a single for loop. But, I don't know why I am getting ArrayIndexOutOfBoundsException. I tried working it out on paper and it seems correct. Can anyone point out my mistake? Thanks!!

The array args has length 0. So the args[0] gives you the exception since there is no '0' element; the length of the array is 0. The elements of the args will [U]never[/U] be [ICODE]null[/ICODE]. Depending on the number of parameters you pass the array args will be created with those parameters. So if you pass 2 parameters… Re: ArrayIndexOutOfBoundsException 14 Years Ago by P00dle Thanks. Very useful advice! I'm now using the following: [CODE]if (args.length > 0) { if (args[0].equals("printer")) { printToFile = false; } } else { printToFile = true; }[/CODE] and it works perfectly. Re: ArrayIndexOutOfBoundsException? 13 Years Ago by jon.kiparsky You have the line number where the error occurred. It looks like you're doing an array read at that line. What is the value of the index you're trying to read at that point? As Norm would say: put in a println statement before the error to see what the value of the variable is at the time the error occurs. Then backtrack to where the variable got … Re: ArrayIndexOutOfBoundsException? 13 Years Ago by flyingcurry [QUOTE=jon.kiparsky;1332914]You have the line number where the error occurred.

What's the value of n there? And more importantly, what's the value of n-1? Re: ArrayIndexOutOfBoundsException? 13 Years Ago by flyingcurry [QUOTE=jon.kiparsky;1332941]I think you're probably right.

And more importantly, what's the value of n-1?[/QUOTE] The value of n there varies depending on what the user has as its input, it is the number of integers the user wishes to enter.

Also, … Re: ArrayIndexOutOfBoundsException? 13 Years Ago by jon.kiparsky Aha. A negative value is probably also going to get you this error as well, right? This is not really a bug, it's a failure to handle input correctly. You're allowing bad input to get in, and your code doesn't know what to do with it. The program deals correctly with the data it's supposed to deal with, but it doesn't know how to enforce that the … Re: ArrayIndexOutOfBoundsException? 13 Years Ago by adams161 After it completes the last line of exception code [code=java] sc.next(); [/code] it continues on the same path as if there had been no exception. it does the array assignment then it assigns your continue loop variable to a value that prompts exit.
