. Random walkers. Write a program RandomWalkers.java that takes two integer command-line arguments r and trials. In each of trials independent experiments, simulate a random walk until the random walker is at Manhattan distance r from the starting point.

Java Questions - (Has 2 Parts). Based on each code, which answer out of the choices "A, B, C, D, E" is correct. Each question has one correct answer. Thank you. Part 1 - Given the following code, the output is __. class Sample{  public static void main (String[] args){  try{  System.out.println(5/0);}catch(ArithmeticException e){  System.out.print("Divide by zero????");}finally{  System.out.println("5/0");  } }} A. Divide by zero????B. 5/0C. Divide by zero????5/0D. 5/0Divide by zero????E. "5/0" Part 2 - Given the following code, the output is __. try{  Integer number = new Integer("1");   System.out.println("An Integer instance.");}catch (Exception e){  System.out.println("An Exception.");} A. An Integer instance.B. An Exception.C. 1D. Error: ExceptionE. None of the options

public static int test(int n, int k) { if (k == 0 || k == n) { return 1; } else if (k>n) { return 0; } else { return test(n-1, k-1) + test(n-1, k); } ww For each of the following calls, indicate the output that is produ test(7,5); test(6,4); test(4,5); test(8,3); test(5,5);

Write a complete Java program that allows users to enter two integer numbers as follows: pleaes Enter the first number:  2 please Enter the Second number:  2   Upon providing the two integer numbers, the users should be given a list of operations to select from, as follows: please choose the operation you want to do with these numbers by Enter a,b or c: a- adding  b- multiplying  c- average Based on the users’ selection, a method should be called to perform the selected operation and return the result. After that the main method should print the result. The output of the program should be as follows in the picture:
