In JDK 1.5, analyze the following code.
``` Line 1: Integer[] intArray = {1, 2, 3}; Line 2: int i = intArray[0] + intArray[1]; Line 3: int j = i + intArray[2]; Line 4: double d = intArray[0]; ``` a. It is OK to assign 1, 2, 3 to an array of Integer objects in JDK 1.5. b. It is OK to automatically convert an Integer object to an int value in Line 2. c. It is OK to mix an int value with an Integer object in an expression in Line 3. d. Line 4 is OK. An int value from intArray[0] object is assigned to a double variable d.
Programming Project 2 asks you, among other things, to write a program that creates a binary file of objects of the class Species. Write a program that reads from a file created by that program and writes the objects to another file after modifying their population figures as they would be in 100 years. Use the method predict- Population of the class Species, and assume that you are given each species’ growth rate.
This project requires only one file to be written. This solution is organized as a sequence of just four method calls in main, one to open an input file for reading Species records, one to open an output file for writing new records, one to do the processing (read a record from the input file and write a record to the output file with the population changed to the projected population after 100 years), and one to close the input and output files.

Write a simple program that uses a loop to sum every third integer from 1 to 10 and outputs the final result. Assign every third integer by incrementing by three so that the values 1, 4, 7, 10 can be summed. Check the program to insure that it works correctly.
