Write a java method to calculate the area of the square(the method should take one parameter

Make sure each program has at least one method in addition to its driver method(main). Or use one driver main method and write method(s) for each of the program. It is a single program not two individual questions so please write both. Write a java program to compute each of the following, use a separate method for each. (i) Calculate the energy of a flight traveling at the speed of light, use e = mc2 take c as the speed (3*108), e = energy and m is mass of the flight. Prompt the user to enter the mass. (ii) Calculate the size of the gravitational force acting between you and your friend as you approach each other (center-to-center 1 meter apart) in the hall way. Use the formula below. Prompt the user to supply the values of M and m. ? = (?∗?∗m)/d2M = Mass of your friend m = Your mass d = center-to-center distance 1m G = 6.67 * 10 -11

Please correct it In java

Write a java program which asks the user to enter name and age and calls the following methods: a. printName(): Takes name as parameter and prints it 20 times using a while loop. b. printAge(): Takes age as parameter and prints all the numbers from 1 up to age. Please strictly follow this format. Note: any extra or missing space / line will lead to test failure. Name: Andy Age: 10 Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy 1,2,3,4,5,6,7,8,9,10 class Main {public static void main(String[] args) {}}

Complete the following program to implement the user interface of the preceding exercise. For simplicity, only the units cm, m, and in are supported. Hint: The value of factor1 or factor2 should be the conversion factor from the selected unit to cm. Ex: If the selected unit is in, factor1 is 2.54 because 1 in = 2.54 cm."in java"

Need two methods in Java to be used in a different class first method returns Julian day from date entered ex:(8/12/21) Second method returns the reformatted date in Julian format

Need help with following Java method: import java.util.Scanner; import java.lang.Math; public class CosineFromScratch { /* The following code demonstrates how to estimate the cosine of a number. Your assignment is to migrate the calculation of the cosine into a new static method named cosine. The method should take one double input and return one double output. Make sure to call the method from main and set the variable estimate equal to the returned value. */ public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("\nGive me a number: "); double x = input.nextDouble(); //Trying to find cosine of this number double correct_cos = Math.cos(x); //START HERE: The following code goes into //the method. //Source for the following: //https://austinhenley.com/blog/cosine.html double num_terms = 10; int div = (int)(x / Math.PI); x = x - (div * Math.PI); int sign = -1; double estimate = 1.0;...

using java language Your program will identify if the shape is a square or a rectangle. Input the length and width of the shape, and display if it’s a rectangle or square, with its area and perimeter. Use the following methods in your program. inputLength() – returns the input length; inputWidth() – returns the input width; analyze(length,width) – based on the parameters length and width, returns a Boolean value if the shape is square or not compute(length,width) – based on the parameters length and width, display the area and the perimeter of the shape.

To increment a variable x in Java, we code the following: x=x+1; x++; x+=1; All of the above are correct.

In Java Determine the output of the following: x = 3; while (x = 25) x = 4 * x

I need answer in java. Thank you

how do i write this in java

Define the method printValue() that takes two integer parameters and outputs the product of all integers starting with the first and ending with the second parameter, followed by a newline. The method does not return any value. Ex: If the input is 3 7, then the output is: 2520 Note: Assume the first integer parameter is less than the second. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 import java.util.Scanner; public class ValuePrinter { /* Your code goes here */ publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumber1; intnumber2; number1=scnr.nextInt(); number2=scnr.nextInt(); printValue(number1, number2); } }
