Task Write a JAVA program that reads the height of a triangle (less than 10) from the user and then calls two void methods named plotTril and plotTri2. Each of the 2 methods should have a parameter for the height of the triangle and use printf inside of nested For loops to produce the output of the respective triangle for the user. Note that the numbers in the triangle are left-aligned. Create a project and class named HW8Firstname Lastname in NetBeans using your actual first and last names to hold your program. For height = 8, plotTril and plotTri2 will print the following triangles respectively. 1 2 4 8 16 1 27 1240 1 2 124 1 524 co 8 1 2 1 A 2 1 2 4 8 16 1 1 2 4 8 16 32 1 2 4 1 2 4 8 1 ΝΗ 2 4 8 16 8 16 32 16 32 64 32 64 128 64 1 2 248 1 2 4 1 2 4 32 16 8 62 16 8 co 1 2 4 1 2 1

java-Find the area of circle using method... Write an application that prompts the user for the radius of a circle and uses a method called circleArea to find tarea of the circle. method method should return the computed area to the caller method.

In this assignment you will demonstrate your knowledge of debugging by fixing the errors you find in the program below. Fix the code, and paste it in this document, along with the list of the problems you fixed.This example allows the user to display the string for the day of the week. For example, if the user passed the integer 1, the method will return the string Sunday. If the user passed the integer 2, the method will return Monday. This code has both syntax errors and logic errors. Hint: There are two logic errors to find and fix (in addition to the syntax errors).Inport daysAndDates.DaysOfWeek;public class TestDaysOfWeek {public static void main(String[] args) {System.out.println("Days Of week: ");for (int i = 0;i < 8;i++) {System.out.println("Number: " + i + "\tDay Of Week: " + DaysOfWeek.DayOfWeekStr(i) )}}}package daysAndDatespublic class DaysOfWeek {public static String DayOfWeekStr(int NumberOfDay) {String dayStr = ""switch (NumberOfDay) {case 1:dayStr =…

You will build a program to manage a race car in this assessment. The code will consist of a for-loop method that will run a car around a race track and cause “wear and tear” on the car. The car will perform x number of laps and will have to make pitstops when it either runs out of gas or needs a tire replacement. The for loop will be simple def wear_tires(car): tire -=1 def use_gas(car): gas -=1 c = Car() # You need to make this part for i in range(100): if the car needs a pitstop: perform pitstop else: wear_tires(c) use_gas(c) # Display the current cars wear in a much better format print(c.tire) print(c.gas) print(“Current Lap is: “ , i) For this task, you will have to use this for loop and build out the two methods in the main Python program. To use the above code, you must build two pieces of information. An abstract Vehicle class A Car class A RaceCar class Each with its methods and variables. This programming will involve using inheritance and abstraction to make a race car…

Q3. Create two methods: one that will reverse the order of the digits in an integer and a second determines if a number is a palindrome (i.e. reads the same front to back) using the following method headers. // Method 1: Takes in an integer and reverses it, e.g., reverse(456) returns 654 public static int reverse(int number) // Method 2: Takes in an integer and returns true if it is a palindrome. Use the reverse method you just wrote to implement this method. public static boolean isPalindrome(int number) Create a test program that asks the user to input an integer and provides feedback on whether the integer is a palindrome or not. Hint: To find the reverse number, use one of the following approaches: • Modify your numerical inputs to a string, then use a for loop to reverse the characters with string concatenation and the charAt() method. Retrieve individual digits and combine them in reverse order using the / and % operators, using ten as a divisor. Combine the digits with either…

Please provide Java source code for following project with proper comments. Write a program that asks the user to enter a distance in meters. The program will then pre-sent the following menu of selections: Convert to kilometers Convert to inches Convert to feet Quit the program The program will convert the distance to kilometers, inches, or feet, depending on the user’s selection. Here are the specific requirements: Write a void method named showKilometers, which accepts the number of meters as an argument. The method should display the argument converted to kilometers. Convert the meters to kilometers using the following formula: kilometers = meters * 0.001 Write a void method named showInches, which accepts the number of meters as an argument. The method should display the argument converted to inches. Convert the meters to inches using the following formula: inches = meters * 39.37 Write a void method named showFeet, which accepts the number of meters as an argument.…

Exercise 5 - Number to Word Make a new class in the Lab2 project called Num2wordthat prompts the user enter a number between 0 and 9 and then displays the corresponding word (i.e. "zero"for 0, "one"for 1, etc.). Use a switchstatement to do this. Include a default case that lets the user know they entered a wrong number. The switch statement has the following syntax: switch (variable) { case value1: // Code that should execute when variable==value1 break; // this prevents it from automatically going to the next case case value2: // Code that should execute when variable==value2 break; // this prevents it from automatically going to the next case default: // Code that should execute when variable has a value that didn't match the above }

Code with comments and output screenshot is must. Thank you!

Write a value returning method that accepts two integer values as arguments and returns the value that is the greater of the two. For example, if 6 and 10 are passed as arguments to the method, the method should return 10. Your program should firstly prompt the user to enter two integers, and display the value that is the greater of the two. using Java programming
