- Create an application in Java that uses card layout with three cards. The first card - a login card - should have two text fields, one for username and other for password. There are two users - Bob and Fred - whose passwords are "mubby and "goolag" respectively. If Bob logs in, switch to a card - the bob card - that has a text field, a text area and two buttons. If the first button is pressed, get the text from the text field and append it to the text area. If the second button is pressed, return to the login card. If Fred logs in, switch to a card - the fred card - that has three buttons. If the first button is pressed, change the background color to green. If the second button is pressed, change the background color to red. If the third button is pressed, return to login card.JavaProblem 2-5 Code ProblemProblem 2-5. Code Problem. Build an application with a text field and two buttons. Type a word or words in the text field. Click one of the buttons. Subtract one from the Unicode value for each character in the typed word(s), then redisplay it. This is a simple encoding technique. When you click the other button, reverse the process to decode the word.In java: ( no stringbuild or chart.append) the program must produce a neatly labeled bar chart depicting the relative values to each other. Note that there is no interactive input and no use of command line arguments. The program at this stage uses values programmed directly into it. The program output must include the original values as well as the bars. The example below shows the relative number of performances of some Broadway musicals (in picture) You choose the width of the chart. In the example above, it's 60, but it can be different. The largest value in your set should use the entire width, the rest of the bars will be proportionately shorter. Since you're assigning the values in the program, you know the maximum and no special logic is required to find it You must compute and display the "scale" of the chart (i.e. how many units one bar symbol represents) Each bar is labeled with the entity and value You may choose any symbol for your bars 3. In…
- There are a number of national and state parks available to tourists. Create a Park class. Include datamembers such as name of park, location, type of (i.e., national, state, local) facility, fee, number ofemployees, number of visitors recorded for the past 12 months, and annual budget. Write separateinstance methods that a) return a string representing name of the park, the location and type of park;b) return a string representing the name of the park, the location and facilities available; c) computecost per visitor based on annual budget and the number of visitors during the last 12 months; and d)compute revenue from fees for the past year based on number of visitors and fee. Also include aToString( ) method that returns all data members with appropriate labels. Create a second class totest your Park class.Create two linkedBag objects of type string in main. Place 5 strings in the first bag and five strings in the second bag. Then your code must test if the two linkedBag objects are equal or not. You must traverse both linkedBags and test each items to see if they are the same. Then you must display a message saying the two linkedBags are the same or different. Using Java compiler.2. Modify the Fahrenheit program so that it displays a button that when pressed causes theconversion calculation to take place. The user will have the option of pressing Enter inthe text field or pressing the button. Have the listener that is already defined for the textfield also listen for the button push.

"def","ghl"."ikl" b. ["def",","gbitikl") C. ["def","ghiltikl") d. "defghükl" e. ["def","ghi"."kI'I "def","ghiltikl" f.6. Use JOptionPane class to show the messages and let user enter the data in the dialog box for this exercise. You need to calculate average score by a game for a team.

Then calculate average score by game, and show to the user.Create a new Java project and make sure "Create project from template" is UNCHECKED). Use a meaningful name such as M4-PA-PatternMaker. Then create a new Java class called PatternMaker in the src folder. Add a main method to this class. The program should follow the guidelines below. The program prompts the user for two input values: An integer value between 2 and 9 (inclusive) for the number of characters in each row to be printed An integer value between 2 and 9 (inclusive) for the number of rows to be printed The number of rows must be smaller than the number of characters per row. If this is violated, repeat 1 and 2 until the user provides the right integers. The first line of the contains a number of `#` and ends with 1. The number of `#` decreases by 1 per line and the number of digits increases by 1 to maintain the same total number of characters per line. The program must use nested for loops to print the pattern. Below are some sample runs. === Pattern Maker === Please…
- java code quation using ExceptionProgramme Leader of ITMB wants to check whether the student number and GSM numberentered by the student for the programming contest is valid or not.Write a Java program to read the Student ID and GSM Number of a student.

Allow for the fact that the user might or might not precede a month or day number with a zero (for example, the user might type "06/24/2012" or “6/24/2012"). Do not allow the user to enter an invalid date, defined as one for which the month is less than 1 or more than 12, or one for which the day number is less than 1 or greater than the number of days in the specified month. Also display the date's ordinal position in the year; for example, 6/24 is the 176th day. In this application, use your knowledge of arrays to store the month names, as well as values for the number of days in each month so that you can calculate the number of days that have passed. Figure shows the output when the user has entered 6/24/2012. Save the application as Date.java Input Enter a date in the format…5.
