I got an assignment to build one program like the question below .. I made a bit of code that has a login and password ..Its also get from the website.. but my friend told me do not meet what the question wants .. is there anyone who can explain to me what the question wants?
I am new in JAVA environment..Thanz

Q1.Many e-commerce websites and intranets require a login and password in order to access data from the site. Write an applet that will ask the user for ID and password through INPUT DIALOG of JoptionPane package. Once the user entered the login and password, the applet will search through an array of Ids and passwords for verification (each array consist of 5 values). The applet then will display an appropriate message. Write the code to create two arrays, one for IDs and one for the corresponding passwords. You will write a loop to progress through the array, searching for a valid ID and password.

Q2.Based on question 1, you are required to accept the user input , login and password through text field and passwordField. Once the user pressed the login and password, the applet will search through an array of Ids and passwords for verification. The applet then will display an appropriate message. Write the code to create two arrays, one for IDs and one for the corresponding passwords. You will write a loop to progress through the array, searching for a valid ID and password.

Q3.Based on question 2, both input, login and password will be from text field. Thepassword is not displayed on the applet. The character ‘*’ is used to displayed instead of the alphanumeric characters. The method setEchoChar() is used to display ‘*’ in the TextField (DO not use passwordField). Once the user pressed the login button, the applet will search through an array of IDs and passwords for verification. The applet then will display an appropriate message.
