Write a Java Program Instructions:Write a method named digitsum that accepts an integer as a parameter and returns the sum of the digits of that number. For example, digitSum(29107) returns19 (2+9+1+0+7). For negative numbers, return the same value that would result if the number were positive. For example, digitSum(-456) returns 15 (4+5+6).Assume that the maximum length of an input number is 10. In case of wrong input, you must print out text "error".Input:25Output:7

The method convertVolume() has an integer parameter. Define a second convertVolume() method that has two integer parameters. The first parameter is the number of gallons and the second parameter is the number of pints. The method should return the total number of pints. Ex: If the input is 9 2, then the output is: 9 gallons yields 72 pints. 9 gallons and 2 pints yields 74 pints. Note: The total number of pints can be found using (gallons * 8) + pints. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 import java.util.Scanner; public class VolumeMethods { publicstaticintconvertVolume(intgallons) { returngallons*8; } /* Your code goes here */ publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intgallonsUsed; intpintsUsed; inttotalPints1; inttotalPints2; gallonsUsed=scnr.nextInt(); pintsUsed=scnr.nextInt(); totalPints1=convertVolume(gallonsUsed);

Please help me! I have a lot of mini problems. I'm not sure how to start After #6, I have other problems. Those are : 7.) Write a method that reads a one-line sentence as input and then displays the following response: If the sentence ends with a question mark (?) and the input contains an even number of characters, display the word Yes. If the sentence ends with a question mark and the input contains an odd number of characters, display the word No. If the sentence ends with an exclamation point (!), display the word Wow. In all other cases, display the words You always say followed by the input string enclosed in quotes. Your output should all be on one line. Be sure to note that in the last case, your output must include quotation marks around the echoed input string. In all other cases, there are no quotes in the output. Your program does not have to check the input to see that the user has entered a legitimate sentence. Notes: This code requires a three-way selection statement and…
A pentagonal number is defined as n(3n-1)/2 for n = 1, 2, …, and so on. Therefore, the first few numbers are 1, 5, 12, 22, . . . . Write a method with the following header that returns a pentagonal number: publicstaticintgetPentagonalNumber(int n) For example, getPentagonalNumber(1) returns 1 and getPentagonal- Number(2) returns 5. Write a test program that uses this method to display the first 100 pentagonal numbers with 10 numbers on each line. Use the %7d format to display each number.
Write a method that returns a random number from alist of numbers passed in the argument. The method header is specified as follows:public static int getRandom(int... numbers)
In this challenge, you need to implement a method which squares passing variables and return their sum. Problem Statement # Implement a method squareSum(double num1, double num2, double num3) in a class SquareSum which takes three numbers, square them and returns their sum. Input: # Three floating point numbers. Output: # Sum of the squares of passing numbers Sample Input # 2, 3, 4 Sample Output # 29
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)…
Write a method named raiseSalary that accepts two integers as an argument and return its sum multiplied by 15%. Write a tester program to test the method. The class name should be your ID (for example: Id12345678). Your answer should include a screenshot of the output. Otherwise, you will be marked zero for this question. Answer:
Write a method call DisplaySineTable(), that prompts the user for a starting value and an step size. The method will calculate and display a table (10 rows) of sine values based on the user input. Use the built-in method Math.Sin() to obtain the sine of an angle. e.g. if the starting value is 0.5 and the step size is 0.03 the method will display the following table:0.50 0.47940.53 0.50550.56 0.53110.77 0.6961
Write a method that returns the lcm (least common multiple) of an unspecified number of integers. The method header is specified as follows: public static int lcm(int... numbers) Write a test program that prompts the user to enter five numbers, invokes the method to find the lcm of these numbers, and displays the lcm.
