exception in thread "main" java.lang.indexoutofboundsexception: index 1 out of bounds for length 1

 0 means you are trying to access index 0 which is invalid, which in turn means the array is empty.
 String[] names = new String[0]; // thats the problem
 String[] names = new String[somelength];//this is true usage

java.lang.arrayindexoutofboundsexception: index 3 out of bounds for length 3

Since in java the first position of an array is 0, if an array has 
length 3 then the last element is in position 2. 

Ex: array = [elem0, elem1, elem2] then the last elem is index 2 
and the array has length 3 

caused by: java.lang.arrayindexoutofboundsexception: 0

The Array is empty.
