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

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...

Write a method called reverseFirstK that accepts an integer k and a queue of integers as parameters and reverses the order of the first k elements of the queue, leaving the other elements in the same relative order. For example, if a queue named q stores [10, 20 30, 40, 50, 60, 70, 80, 90], the call of reverseFirstK (4, q):should change the queue to store [40, 30 20, 10, 50, 60, 70, 80, 90]. If k is 0 or...

JAVA Write a method that accepts a String as an argument. The method should use recursion to display each individual character in the String. Then, modify the method you just wrote so it displays the String backwards. The following code does not correctly display the String backwards. It merely moves the first character of the String to the end: public static void displayCharacter(String s) { if(s.length() == 0) return; else ...

Write a method named printGrid that accepts two integer parameters rows and cols. The output is a comma-separated grid of numbers where the first parameter (rows) represents the number of rows of the grid and the second parameter (cols) represents the number of columns. The numbers count up from 1 to (rows x cols). The output are displayed in column-major order, meaning that the numbers shown increase sequentially down each column and wrap to the top of the next column...

Write a method called printReverse() that takes a string and uses recursion to print the contents of the string in reverse order. The string itself should not be reversed; it must be left in its original form. The method has the following header: void printReverse(String s, int i) where s is a reference to the string, and i is an integer parameter that you may use as you see fit. You do not need to code up this method as...
