The answer for your code is #4. Exception raised:java.lang.ArrayIndexOutOfBoundsException: 2

This is because, in your code, you lack some data or no data at all where your statement argv[2] will refer to. Accessing data in an array is through its index number. Lets say you have an array of integers.

                int[] mynum=new int[3];

then we will put values to our array.

mynum[0]=1; — the [0] is the index in our array where the number 1 is stored



Now, let say we want to print/show the value that is stored at array index 3. 


this code will give an error Exception raised:java.lang.ArrayIndexOutOfBoundsException: 3 this is because, in our array, the maximum number in our array index is only 2  and you want to access the data in array index 3 where theres no available data on it. 

Based in your code, there's no value/data stored in your argv[].
