ArrayIndexOutOfBoundsException though array has value - arrays

Question

I tried to do validation by comparing two array values using IF condition as follows:
if (!bomDataArray[1].trim().equals(agileDataArray[0].trim())) {
updateItemComments(bomDataArray[17], Constant.DESCRIPTOIN_MISMATCH);
}
I am able to print the value using sysout in server.
Code:
System.out.println("bomDataArray[1].trim().equals(agileDataArray[0].trim() ---> "+bomDataArray[1].trim() + "---" +(agileDataArray[0].trim()));
Ouput in Server:
[2018-02-26T17:22:51.158+0800] [Payara 4.1] [INFO] [] [] [tid: _ThreadID=28 _ThreadName=http-thread-pool::http-listener-1(5)] [timeMillis: 1519636971158] [levelValue: 800] [[
bomDataArray[1].trim().equals(agileDataArray[0].trim() ---> CAPACITOR, CERAMIC MULTILAYER, SURFACE MOUNT (CHIPS)---CAPACITOR, CERAMIC MULTILAYER, SURFACE MOUNT (CHIPS)]]
After running this, the system throws ArrayIndexOutOfBoundsException.

Please help me to understand which went wrong in this?

Answer 1

If the code you posted is in ZhuhaiBomComparisonParserPlugin.java on line 226 as the stack trace says then the problem is that you're trying to access the second element of the array bomDataArray (with index 1) but the array has only 1 element or is empty. You need to find out why the array has less then 2 elements.
Btw, this is clearly error in your application code and has nothing to do with Payara Server your application is deployed to. You need to fix your code.
