In Java Write a java program to draw a triangular-shaped figure that is based on the user’s input. Your program should ask the user for a number between 1 to 9. If the user inputs a number out of the specified 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: 99 Invalid Entry Please 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

In java    Write a program that computes the average of 5 students grades which are entered by the user.

In C# code: Write a program that will help an elementary schoolstudent learn multiplication. Use a Random object to produce two positive one-digitintegers. The program should then prompt the user with a question, such asHow much is 6 times 7 The student then inputs the answer. Next, the program checks the student’s answer. Ifit’s correct, display the message "Very good!" and ask another multiplication question.If the answer is wrong, display the message "No. Please try again." and let the studenttry the same question repeatedly until the student gets it right. A separate methodshould be used to generate each new question. This method should be called oncewhen the app begins execution and each time the user answers the question correctly.Program will stop any time students enter -1. One problem in CAI environments is student fatigue. This can be reduced by varyingthe computer’s responses to hold the student’s attention. The program should usevarious comments to be displayed for each…

Java Calculating the User's Sum Write a complete program that reads in numbers and calculates the sum of the numbers in that range. Code Specifications In the main method, read input from the user. Read in two integers from the user: a lower end of the range and an upper end of the range. Check if the numbers are valid: the lower number cannot be greater than the upper number. If the numbers are invalid, use a loop to ask for new numbers. Continue looping until you get two valid values. Write a method called calculateTheSum.  The method takes in a lower and upper end of the range. The method calculates the sum of all values from lower (inclusive) to upper (inclusive). Invoke the method from main the output the result. Test Cases I recommend testing your code using the test cases below. I've listed the user inputs along with a sample of the result. User Inputs Result lower = 10, upper = 1 the program should ask for new input lower = 5, upper = -5 the program should ask…
