Write a non-static java method factorial. It should return the product of all the numbers from 1 to the parameter n. For example, factorial(5) should return 120 because 1 x 2 x 3 x 4 x 5 = 120.

Write a method named factorial that accepts an integer n as a parameter and returns the factorial of n, or n!. A factorial of an integer is defined as the product of all integers from 1 through that integer inclusive. For example, the call of factorial(4) should return 1 2 3 4, or 24. The factorial of 0 and 1 are defined to be 1. You may assume that the value passed is non-negative and that its factorial can fit...

In Java Write a method factorial that accepts an integer parameter n and that uses recursion to compute and return the value of n factorial (also known as n!). Your method should throw an IllegalArgumentException if n is negative. Several calls and their return values are shown below. Call Output factorial(0); 1 factorial(1); 1 factorial(3); 6 factorial(5); 120 factorial(10); 3628800 factorial(-4); IllegalArgumentException

JAVA 1.Write a static method named getMaxEven(numbers) which takes an array of positive integers as a parameter. This method calculates and returns the largest even number in the list. If there are no even numbers in the array, the method should return 0. You can assume that the array is not empty. For example: Test Result int[] values = {1, 4, 5, 9}; System.out.println(getMaxEven(values)); 4 System.out.println(getMaxEven(new int[]{1, 3, 5, 9})); 0 public static int --------------------------------------------------------------------------------- 2.

Write a static method named swapHavles that takes an ArrayList of integers as a a parameter and returns a new ArrayList that has every element in the second half of the original ArrayList swapped with every element in the first half of the original ArrayList. Note: • You can assume that the ArrayList passed to this method as a parameter always contains an even number of elements and will always contain at least two elements. For...

Change the factorial method to return a BigInteger. You can leave the parameter value alone (ie, the parameter will remain an integer). You'll need to modify the method to use BigInteger objects and instance methods. Hint: remember that you can easily form Strings from numerical values by concatenating the numerical value with the empty String "". For Example: String s = 5 + ""; •What happens when you rerun your loop in main? Do you get the correct answers? import...

4. [Tests basic knowledge of recursion] Write a recursive static Java method that accepts an array arr of integers argument returns a list of all permutations of these integers. (A permutation of a sequence of integers is a re-arrangement of the integers. For example, one permutation of 1, 3, 4, 8, 2 is 3, 1, 2, 8, 4.) For this problem, you may assume that the input array contains no duplicate entries. Your method should return an ArrayList of int...
