Answer the following statement true (T) or false (F)
Write a program that reads a file of numbers of type int and writes all the numbers to another file, but without any duplicate numbers. Assume that the numbers in the input file are already ordered from smallest to largest. After the program is run, the new file will contain all the numbers in the original file, but no number will appear more than once in the file. The numbers in the output file should also be sorted from smallest to largest. Your program should obtain both file names from the user. Use either a text file or a binary file. For the text-file version, assume one number per line. For the binary-file version, use numbers of type int that are written using writeInt.
This project is similar to Practice Program 1: data files need to be created before any processing can be done and it is easier to work with binary files than text. So a good approach is start with the binary file classes from Project 1 and modify them so data files can be created and displayed, then write the program to process the binary data files. Note that a separate program to display data files is necessary to view the files created by the program that removes the duplicates. If students do not have the programs from Project 1 to work from, then they could start with files from the text, BinaryOutputDemo.java (Listing 10.5) and Doubler.java (Listing 10.8). After all the binary file programs are written and tested, it is easier to develop the programs to create, read and process text files. Just as with Project 1, the code for setting up the input and output streams needs to be changed, the while-loop condition needs to be changed to end when a null string is read, and text Strings in the data file must be changed to ints by using the parseInt method in the Integer class
