Write a program called LoopMethod (main method) that contains a method called printNums (method name) that prints the numbers from a specified start to end value. a) The main method will do the following: • asks the user for start and end number (int type). • calls the printNums methodb) The printNums method will do the following: • receives start and end number (parameters)• prints from the start to the end number using a loop Sample Run: Input start number: 3Input end number: 93 4 5 6 7 8 9Input start number: 9Input end number: 219 10 11 12 13 14 15 16 17 18 19 20 21
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…
The following code segment has been created. the code can be placed in a method. The code keeps asking the user to enter a double value until the user provides a valid input. Once a valid input is entered the loop ends and the method returns the value However it has an infinite loop. Fill in the blank so that the method works. int done = 0; double input = 0; while (done!- -1) try System.out.print("Enter an double: "); input - kb.nextDouble(); catch(Exception e) System.out.println("You did not enter a valid input "); kb.nextline(); return input;
Java programming The US dollar = 0.82 Euros and 1.21 Canadian dollars.Write the following methods to convert US dollars to Euros and to Canadiandollars: *** A method prompting the user to select an option (to convert to Euros orto Canadian dollars) and returns the option to the main method.
This program will ask a user to enter their favorite color. Your program will tell the user what their “spirit animal” is based on the color entered. (Or you can do something similar but different – like online quizzes that tell you what kind of potato you are.) You will create a static method called getAnimal that takes in a single String and returns a String. In this method, you will write the code that will determine which animal gets returned. You may choose the possible colors and animals (or you may choose something else ridiculous for this program) but you must have at least 4 options for the user. For example, if they enter “red”, you might return “Tiger”. Make sure to include a response for incorrect inputs. In the main method you will give the program explanation, ask for input (favorite color), capture the input, call the getAnimal method (passing in the user’s input), and print the result. No try/catch blocks or loops are necessary. The static method should contain…
The area of a rectangle can be computed using the following formula: area = width * height; Write a method that returns the area of a rectangle using the following header: public static double getArea(double width, double height) Write a main method that prompts the user to enter the width and height of a rectangle and displays its area. Input example: 1.2 3.4 Output example: The area of the rectangle is 4.08

Where do I place a return method for finding the area of a square, triangle, and rectangle? Also are the math equations correct for each shape? //PSEUDOCODE //Write a program that demonstrates method overloading by defining and calling methods that return the area //of a triangle //a rectangle //a square private static void area(float a) { System.out.println("The area of the square is " + String.format("%,.2f", Math.pow(a,2)) + " sq units"); } private static void area1 (float a, float b) { System.out.println("The area a of the rectangle is " + String.format("%,.2f", a * b) + " sq units"); } private static void area (float a, float b) { double c = 0.5 * (a * b); System.out.println("The area of the triangle is " + String.format("%,.2f", c) + " sq units"); } public static void main(String[] args) { area(5); area1(05,21); area(05,05); } }
