Hi i have written following code and getting this error

File fileDir = new File(srcdir);
String[] fileList = new String[100];
fileList = fileDir.list();
for(int i=0; fileList.length>0; i++){
String currFile = srcdir + fileList;
//String fname = new String(fileList[i]);
System.out.print("String file name is " + currFile);
//System.out.print("file name is " + fileList[i]);
ERROR : java.lang.ArrayIndexOutOfBoundsException
I'm new to java.
Please tell me where i'm going wrong.
any help would be great.

There are several errors in your code:
String[] fileList = new String[100];
fileList = fileDir.list();
Here you point the fileList reference to a String[] object, and then immediately point the reference to another object. This is a useless creation of an object... the #1 cause of slow Java code.
Write just this instead:
String[] fileList = fileDir.list();
for(int i=0; fileList.length>0; i++){
The condition fileList.length > 0 will forever be true or false. the condition should be i < fileList.length.
I think those suggestions should get you started...
