Kinetic energy is the measure of the work that an object does by virtue of its motion. It is best illustrated by the formula: KE = 0.5 mv² Create a java class that will call a method that will compute for the kinetic energy. Sample output: Enter mass of an object: 54 Enter velocity of an object: 2.87 The kinetic energy of an object is: 222.40 joules

ISP- Java A pedometer treats walking 2,000 steps as walking 1 mile. Write a program whose input is the number of steps, and whose output is the miles walked. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("%.2f", yourValue); Your program must define and call a method: public static double stepsToMiles(int userSteps) Ex: Ex: If the input is: 8790 the output is: 4.40
Java Programming. Needs to be done with loops. Define a public static method called printPyramid(). This method should have publicstatic as its visibility modifiers. It should not return a value. It has a single integer parameter.When printPyramid() is called with an integer value, it should print a pyramid with a heightof that value.For example, if we call printPyramid() with an integer value of 5, then the following shouldbe displayed in the output console.** ** * ** * * ** * * * *You will have to use multiple for loops (consider nested for loops) to write this method.❏ In your main method, you should ask the user for the desired height of the pyramid. The usershould provide a value greater than 1. If the user does not provide a valid value, you should forcethe user to continue entering values until they enter a correct one.Then, call the printPyramid() method with the height given by the user.
in java Write a program to calculate item’s sale price 1)Ask user to enter the name of item e.g t-shirt 2)Ask user to enter the color of the shirt they want to buy 3)Ask user to enter the item’s price e.g 10, 100, 200 4)Write a method to calculate discounted price 1)If item’s price is more than or equal to 100, get 10% discount 2)Item’s color must be ‘blue’ 3) Return discounted price 4) If less than 100 or not blue, no discount 4) Mainline should display, item name, color and the discounted price
IN java explain: Define a method named coinFlip that takes a Random object and returns "Heads" or "Tails" according to a random value 1 or 0. Assume the value 1 represents "Heads" and 0 represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls method coinFlip() repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than 0. Ex: If the random object is created with a seed value of 2 and the input is: 3 the output is: Heads Tails Heads Note: For testing purposes, a Random object is created in the main() method using a pseudo-random number generator with a fixed seed value. The program uses a seed value of 2 during development, but when submitted, a different seed value may be used for each test case. The program must define and call the following method:public static String coinFlip(Random rand) code provided: import java.util.Scanner;import java.util.Random; public class…
Solved in Java Write a method maxMagnitude() with two integer input parameters that returns the largest magnitude value. Use the method in a program that takes two integer inputs, and outputs the largest magnitude value. Ex: If the inputs are: 5 7 the method returns: 7 Ex: If the inputs are: -8 -2 the method returns: -8 Note: The method does not just return the largest value, which for -8 -2 would be -2. Though not necessary, you may use the absolute-value built-in math method. Your program must define and call a method:public static int maxMagnitude(int userVal1, int userVal2) import java.util.Scanner; public class LabProgram { /* Define your method here */ public static void main(String[] args)…
A pentagonal number is defined as n(3n−1) ∕ 2 for n = 1, 2, . . ., etc.. Therefore, the first few numbers are 1, 5, 12, 22, . . . . Write a method with the following header that returns a pentagonal number:public static int getPentagonalNumber(int n) For example, getPentagonalNumber(1) returns 1 and getPentagonalNumber(2) returns 5. In Java, Write a test program that uses this method to display the first 100 pentagonal numbers with 10 numbers on each line. Numbers are separated by exactly one space.
ISP- JAVA A “jiffy” is the scientific name for 1/100th of a second. Given an input number of seconds, output the number of "jiffies." Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("%.2f", yourValue); Your program must define and call a method: public static double secondsToJiffies(double userSeconds) Ex: Ex: If the input is: 136 the output is: 3600.0
A regular polygon is an n-sided polygonin which all sides are of the same length and all angles have the same degree (i.e.,the polygon is both equilateral and equiangular). The formula for computing thearea of a regular polygon is given below: Write a method that returns the area of a regular polygon using the following header:public static double area(int n, double side)Write a main method that prompts the user to enter the number of sides and theside of a regular polygon and displays its area. Here is a sample run: Enter the number of sides: 5 ↵EnterEnter the side: 6.5 ↵EnterThe area of the polygon is 72.69017017488385
basic java please Write a method called findTip that finds the value of a meal as a double after adding the tip to the cost. Then return this value to the calling function. For example findTip(120.10, 5) would 126.105 because that is a 5% tip. While findTip(48.0, 15) would return 55.2 because that is a 15% tip. Note that the bill is a double while the tip is an int. Don’t worry about rounding to two decimal places, just return the full value as a double.
Write a Java program that randomly generates a three-digit lottery number and prompts the user to enter a three-digit number. Each digit in the number is in the range between 0 to 9 with both 0 and 9 possible numbers. Write a method named getPrize() to determine which prize the user wins following the rules shown below. The method getPrize() should return an integer representing which prize was won such as 1 for first, 2 for second, etc. It should return -1 if no prize was won.
Writing Methods that Return a Value in Java In this lab, you complete a partially written Java program that includes a method that returns a value. The program is a simple calculator that prompts the user for two numbers and an operator ( +, −, *, /,or% ). The two numbers and the operator are passed to the method where the appropriate arithmetic operation is performed. The result is then returned to the main() method where the arithmetic operation and result are displayed. For example, if the user enters 3, 4, and *, the following is displayed: 3.00 * 4.00 = 12.00 The source code file provided for this lab includes the necessary variable declarations, and input and output statements. Comments are included in the file to help you write the remainder of the program. Instructions Write the Java statements as indicated by the comments. Execute the program Tasks Defined performOperation() Input / output tests Multiplication input / output test Division input / output test Subtraction…
