System specifications: 1. Interface one: Main page This interface will act as a landing page for the system. It should have two buttons to open the other interfaces. 2. Interface two: Registration page This interface will have form elements to capture the athlete's first name, surname and the time (in seconds). There should be two buttons, one for going back to the main page (interface one) and another for checking the form inputs and saving the 1 HPXS200-1-Jan-Jun2023-T\&L- Week 1- Solution s-RM-V.2-23022023 form details. You need to add additional labels to show invalid input messages. These labels should be invisible by default and need to be visible if the corresponding input is invalid. Text on these labels must have a red colour. Checking the form inputs involves ensuring that all three inputs are filled and checking that the time entered is in seconds and is an whole number (ignore milliseconds). If any of the inputs are invalid, make the corresponding label for the error message visible and display an appropriate message. Once you are happy with the user inputs, you must add the code to save the input data. For simplicity, save the data on a txt file. The name of the file should be "athlete.txt". Use a semicolon ",;" symbol to separate the different fields of a student record (e.g. "Joe; Doe;19") and add a new athlete record on a new line. 3. Interface three Students' list On this interface, you need to retrieve the list of athletes from the athlete.txt file you saved data from interface 2. Sort the athlete's performance on a list, starting with the fastest athlete and display them on this interface in a tabular The main components of this interface are a button for opening the main page (interface 1) and any element for showing the list of students. Requirement: You are required to Implement the above system using Java JFrame..
