Write a Java program which reads a text file and writes the content into a new file. During the read-write process, convert all the upper case letters into lower case ones. In other words, your programming task is to create a new file with the same content of the original file, only that all the upper case letters are converted into lower case ones in the new file. Create your own text file to test your program. You will need to submit both the Java file and the text file during submission.

Note: In DrJava, please make this simple as possible with screenshots of compiled results, screenshots of program code not just text, and description of what each line or section of line does. Thanks.
