Write a program using the graphics module which draws in the center of a window of size 250 x 250 pixels with the title "Simple interaction", a centered red filled square of side 2*x pixels where x comes as input from an entry field placed somewhere in the window. After the square is drawn if the user clicks somewhere on the window the program should terminate. The order of user actions are the following: enter integer value in entry field, click somewhere on the widow, draw red filled square, click somewhere again, close the window.

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.

Write a program that lets the user play the slot machine (https://en.wikipedia.org/wiki/Slot_machine).A slot machine features a screen displaying three or more reels. To play, the user inserts money and activates the machine by means of a lever or button (either physical or on a touchscreen). The reels then spin and stop to rearrange the symbols. If the rearranged symbols match a winning combination, the player earns points based on a pay table. Symbols vary depending on the theme of the machine. Classic symbols include objects such as fruits, bells, and stylized lucky sevens.In this assignment, we slightly modify the operating mode of the slot machine as follows. Instead of the user manually activating the machine every time they want to play, the program will automatically play on behalf of the user multiple times. The user can choose from the following menu:1-> Play n times. The machine will repeatedly play n times.2-> Play until the credit gets below a minimum value. The…

Using the Circle2D class you defined in Exercise 8.18, write a program that enables the user to specify the location and size of two circles and displays whether the circles intersect, as shown in Figure 12.20. Enable the user to point the mouse inside a circle and drag it. As a circle is being dragged, the program updates the circle’s center coordinates and its radius in the text fields.

Create a simple program that includes JFrame, JPanel, JLabel, JFields, JTextArea, and JButton. The program should ask the user for the following input: First name • Last name Middle name • Mobile number E-mail address. Two (2) frames will be used in this program: OUTPUT and INPUT. The following conditions must be satisfied by the program. Input Frame: Set the window name to INPUT. • The input frame should collect all the details listed on Step 2. It should contain Submit and Clear All buttons. • When the Submit button is clicked, it should generate the output frame and disable the Submit button. • When the Clear All button is clicked, it should clear all the content that were entered by the user in the input frame, and close the output frame if it is open. Output Frame: • Set the window name to OUTPUT. • The output frame should display all the details that were entered by the user with the corresponding label. The output frame should contain an Okay button. When the Okay button is…

Create a Java  application which will take an infix algebraic expression as an input from user. It will check that whether it is a valid expression or not. Then It will be converted into postfix expression, and at the end it will be evaluated and print the result of the expression. For example:if input is: (3+5)*(7output: it is invalid.If input is: (3+5)*7 , displayPostfix form: 35+7*Answer: 56.

using paintComponent(Graphics g) Write a program in java that, for four points A, B, C and P, • draws a triangle formed by ABC and a small cross showing the position of P; • displays a line of text indicating which of the following three cases applies: P lies (a) inside ABC, (b) outside ABC, or (c) on an edge of ABC. The user will specify the four points by clicking. please don't copy from chegg, correct answer gets up voted thanks.

A class plays a fishing game in which a large tub is filled with plastic fish that are identical, except that some are red and the rest are white. A student is blindfolded and pulls 10 fish out of the tub. The student removes the blindfold, writes down how many of each color fish she got, and then puts the fish back in the tub. Each student takes a turn. The results are shown in the table.  Display these data in a dot plot.  Write and answer (to the extent possible) at least three questions about the data display in part (a); include at least one question at each of the three graph-reading levels discussed in the reading.

In the Java programming language, write a program that opens a 400x200 window with two 200x200 buttons. One button says "Close" - which closes the program, and on the other the number "16". Each time you press this button, the number is halved until 1. When 1 is reached the button does not change anymore.
