Need help with this java practice question. Need to complete main method.

Adding line numbers to the file.

1. Begin with the supplied file Template.java.

public class Template { static final String INPUT_FILE = "test.txt"; static final String OUTPUT_FILE = "output.txt"; public static void main(String[] args) { }//main } 2. Complete the main method so that it will read in the supplied file test.txt and write out a modified version of this file as output.txt. (These two names are predefined for you as global constants.) The output file should be the same as the input file, except that every line should have a line number added to the front, in the format shown below. The supplied file test.txt contains: This is the top line

The previous one is blank. Short one. This is the last one. Your program should create an output file output.txt which contains: 1: This is the top line 2: 3: The previous one is blank. 4: Short one. 5: This is the last one.
