Please help me with this. Really need help!!!

3.13 Ch 3 Program, part 2: File Name and Type This program determines the name and type of a file when given its string. For example, the file README.txt has the name README and the type is txt. (1) Develop the getFileName and getFileType methods. a) Copy the following method stubs into your FileNameAndType class. * Returns of the name of the file. Hint: look up indexof and substring in the String Class * @param file The complete file String * @return The name of the file */ public static String getFileName (String file) { //TODO: FILL IN BODY * Returns the type of the file as a lower case string. Hint: look up indexOf and substring in the String Class * @param file The complete file String * @return The type of the file public static String getFileType(String file) { //TODO: FILL IN BODY b) Before implementing the getFileName and getFileType methods, think about examples of values (test cases) that might be passed in to file. Copy the following methods into your FileNameAndType class and replace the /*FIX ME* / with 3 different calls to the getFileName and getFileType methods. Each call should test a different example input to the method. You should have a minimum of 3 tests, but you may have more. /** * Runs tests on the testGetFileName method. */ public static void testGetFileName() { System.out.println(/*FIX ME*/); System.out.println(/*FIX ME*/); System.out.println(/*FIX ME*/); /** * Runs tests on the testGetFileType method. */ public static void testGetFileType() { System.out.println(/*FIX ME*/); System.out.println(/*FIX ME*/); System.out.println(/*FIX ME*/); c) Implement the getFileName and getFileType methods and use the testGetFileName and testGetFileType methods to test them before submitting, respectively. However, be sure to remove or comment out your test method calls before submitting c) Implement the getFileName and getFileType methods and use the testGetFileName and testGetFileType methods to test them before submitting, respectively. However, be sure to remove or comment out your test method calls before submitting. (2) Using the following comments, complete the main method. You should create an instance of a Scanner class (Scanner object) with the argument of System.in. Then, for the next three file strings in your Scanner instance, print out (each on their own line) the strings generated by calling getFileName and getFileType. Given the following input: Homework.txt Resume. PDF HelloWorld.java The output should be: Name: Homework, Type: txt Name: Resume, Type: pdf Name: HelloWorld, Type: java
