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)*(7 output: it is invalid. If input is: (3+5)*7 , display Postfix form: 35+7* Answer: 56.

java Write a program that prompts the user to enter a point (x, y) and checks whether the point is within the rectangle centered at (0, 0) with width 10 and height 5. For example, (2, 2) is inside the rectangle and (6, 4) is outside the rectangle, as shown in the Figure. (Hint: A point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its vertical distance to (0, 0) is less than or equal to 5 / 2.) Here are sample runs of the program: Sample 1: Enter a point with two coordinates: 2 2 Point (2.0, 2.0) is in the rectangle Sample 2: Enter a point with two coordinates: 6 4 Point (6.0, 4.0) is not in the rectangle Analysis: (Describe the problem including input and output in your own words.) Design: (Describe the major steps for solving the problem.) Coding: (Go over your code step by step) Testing: (Describe how you test this program). In other words run your code with sample outputs.
In Java Write a java program to draw a triangular-shaped figure that is based on the user’s input. Yourprogram should ask the user for a number between 1 to 9. If the user inputs a number out of thespecified range, the program should display an error and prompt the user for a valid input.Sample Run:Please enter a number between 1 to 9: 99Invalid EntryPlease enter a number between 1 and 9:• The triangular shaped figure for an input of 1 is:1• The triangular shaped figure for an input of 2 is:1 21• The triangular shaped figure for an input of 3 is:1 21 321• The triangular shaped figure for an input of n is:1 21 321...n…. ... 1
Write a java program to create a "Calculator Quiz-Test" application to perform addition of three random questions. When the program starts your application should display 2 random numbers ranging from 1-100 and ask the user to enter the addition of these 2 numbers (similarly you have to create 2 more sets of questions) and finally you should display the number of correct and incorrect questions and display the total marks as well. A correct answer will earn 10 marks and an incorrect answer will get - 5 (negative mark). When the program ends you should display the following, ) Number of correct and incorrect questions 2) Total marks obtained 3) The answer for all generated questions.
Java. Write an application that determines whether a phrase entered by the user is a palindrome. A palindrome is a phrase that reads the same backward and forward without regarding capitalization or punctuation. For example, “Dot saw I was Tod”, “Was it a car or a cat I saw”, and “Madam Im Adam” are palindromes. Display the appropriate feedback: You entered a palindrome or You did not enter a palindrome. An example of the program is shown below: Enter a stringWas it a car or a cat I sawYou entered a palindrome
Hello, Please write a Calculator program in Java using the JavaFX libraries as we discussed in class. At a minimum, your calculator should handle addition, subtraction, multiplication and division of integer numbers. So basically you should be able to input a number, click an operation (+ - * /) button, then enter another number and hit = and you should see the result show up in the calculator display. For part 2 add the functionality to the buttons. So that as a minimum your calculator programs should be able to handle the user inputting a multi digit integer, press + or - or * or /, then input another multi digit integer and then press the = button and the answer gets printed in the text label in your Calculator GUI.

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 an expression that will cause the following code to print "Equal" if the value of sensorReading is "close enough" to targetValue. Otherwise, print "Not equal".
