Answer 1

You code tries to call the toString() method of an int value. In Java, int is a primitive type and has no methods. Change the line:

Array[i] = intArray[i].toString();

to

Array[i] = String.valueOf(intArray[i]);

and the code should run. By the way, you should use lowerCamelCase for variables and fields.

Edit: For what it's worth, String.valueOf(int) is a bit faster than Integer.toString(int) on my system (Java 1.7).
