Retail StoreSuppose you have been consulted by a retail shop around your area to build a simple calculator. The calculator must be able to perform arithmetic operations (+, -, *, /) on integers. The program receives an expression from the user. The expression is structured as follows: integer input followed by an operator and another integer input from user prior to displaying the final result. Write a Java application that can perform the above expression. Create a method that takes two parameters and performs an arithmetic operation on the passed values. Your final output should consist of the expression and the result.
In Java code do the following:Write a method that accepts a String as an argument. The method should use recursion to display each individual character in the String:
basic java please Write a void method named emptyBox()that accepts two parameters: the first parameter should be the height of a box to be drawn, and the second parameter will be the width. The method should then draw an empty box of the correct size. For example, the call emptyBox(8, 5) should produce the following output: ***** * * * * * * * * * * * * ***** The width of the box is 5. The middle lines have 3 spaces in the middle. The height of the box is 8. The middle columns have 6 spaces
Language: JAVA Keep Guessing Write a program that plays a number-guessing game to guess a secret number randomly generated within the range 1 and 10. The user will get as many numbers of tries as he/she needs to guess the number. Tell the users if their guess is right or wrong and if their guess is wrong let them try to guess the number again. You must generate the secret number using the Java Random class. When the user guesses a number he/she will have to take an input of his guessed number from the keyboard. The user will have to take as many inputs as needed to guess the correct secret-number. That means the code will keep looping as long as the guess is different from the secret number. Use a while loop to prompt the user to guess again if the guess is wrong. Create a class named NumberGuessingGame which will contain the main method, write all your code in the main method. Sample input and output: Suppose the random number generated is 6. I have chosen a number between 1…
Math: pentagonal numbers) A pentagonal number is defined as n(3n-1)/2 , for n = 1,2, . . ., and so on. Therefore, the first few numbers are 1, 5 ,12, 22, ... Write a Java program with an object class called Pentagon and a test class called testPentagon. The Pentagon object class must contain a method with the following header that calculates and return a pentagonal number: public int calcPentagonalNumber(int n) Use the formula: n(3n-1)/2 In the test class: Make use of the calcPentagonalNumber(n) method in the Pentagon object class and display the first 100 pentagonal numbers with 10 numbers on each line. NOTE: NO marks if the pentagonal number is calculated in the test class. Your solution must be an object-oriented solution
Financial Application:• Write a program that computes future investment value at a given interest rate for aspecified number of months and prints the report shown in the sample output. • Given the annual interest rate, the interest amount earned each month is computedusing the formula: Interest earned = investment amount * annual interest rate /1200 (=months * 100) • Write a method, computeFutureValue, which receives the investment amount, annualinterest rate and number of months as parameters and does the following: o Prints the interest amount earned each month and the new value of theinvestment (hint: use a loop). o Returns the total interest amount earned after the number of months specified bythe user. The main method will:o Ask the user for all input needed to call the computeFutureValue method.o Call computeFutureValueo Print the total interest amount earned by the investment at the end of thenumber of months entered by the user. Sample Program runningEnter the investment…

JAVA PROGRAMMING ONLY CODE!!!! (one java file which contains 2 methods) Any other file formats will Write a program that calls these two methods as described below printPattern (int a) – A void method which takes user input as a parameter and generates 5 multiples of the input and stores the multiples in the array and finally prints the numbers in the following pattern (See expected output)Note: Use the array to print the numbers Enter a number : 4 Multiples of 4 are stored in an array – [4,8,12,16,20] 4 4 8 4 8 12 4 8 12 16 4 8 12 16 20 printLarge (int a, int b) – A method which takes user input as a parameter and returns all the numbers between the two numbers in an array to the main method. Note: Print the array from the main method Enter two numbers : 5,10 The numbers between 5 and 10 are - 6,7,8,9

Here are some well-known palindromes: Able was I, ere I saw Elba A man, a plan, a canal, Panama Desserts, I stressed Kayak Write a boolean method that uses recursion to determine whether a string argument is a palindrome. The method should return true if the argument reads the same forward and backward. Demonstrate the method in a program.
