Write a static method called isEven that takes an integer as a parameter and returns true if the integer is even and false otherwise.

java

java Create a method called next3() that will take an int argument and print the three numbers that come after the given number. The next3() method is already called in the main method. Print in the following format:   $number1 $number2 $number3   The three next numbers are printed on the same line with spaces between them This is a void method with an int parameter

java program give comments for the code please.   Write a program that calls these two methods as described below A void method that ask user to input an integer to be a parameter and prints following pattern. For example, the user entered 5 as input, the pattern will be:   5 4 3 2 1 5 4 3 2 5 4 3 5 4 5       b. A void method takes Sting as a parameter. Then print out all the vowels in the string. Example given below: Please enter a String. Christopher Vowel in the String:ioe

Write a program called AveMethod (main method) that contains a method called threeAve (method name) that computes the average of three numbers.  a) The main method will do the following: • asks the user for 3 number (double type). • calls the threeAve method• print the average of the three numbersb) The threeAve method will do the following: • receives 3 numbers (parameters)• calculate the average of the three numbers• returns the average Sample Run: Input the first number: 2.5Input the second number: 3.5Input the third number: 6.6The average is 4.2

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;…

Define a method findWinningPrize() that takes one integer parameter as the lottery number, and returns the prize as an integer. The prize is returned as follows:   If lottery number is 178 or 286, prize is $6000. If lottery number is 296 or 446, prize is $12000. Otherwise, prize is $0. Ex: If the input is 178, then the output is:   6000

public class utils { * Modify the method below. The method below, myMethod, will be called from a testing function in VPL. * write one line of Java code inside the method that adds one string * to another. It will look something like this: * Assume that 1. String theInput is 2. string mystring is ceorge неllo, пу nane is * we want to update mystring so that it is неllo, пу nane is Ceorge */ public static string mymethod(string theInput){ System.out.println("This method combines two strings."); Systen.out.println("we combined two strings to make mystring); return mystring;

Write a method that receives three double numbers and returns their average. You can use any valid method name and variable names.

Write a method (with a parameter n), n: integer type that prints numbers from 1 to n. The print out should be 5 numbers per line. All the output numbers should be aligned well. Call the method with n=13 and n=10 in the main()
