Task #1 Tracing Recursive Methods 1. Copy the file Recursion.java (see Code Listing 16.1) from the Student Files or as directed by your instructor. 2. Run the program to confirm that the generated answer is correct. Modify the factorial method in the following ways: a. Add these lines above the first if statement: int temp; System.out.println ("Method call -- " + "calculating " + "Factorial of: " + n); Copyright © 2019 Pearson Education, Inc., Hoboken NJ b. Remove this line in the recursive section at the end of the method: return (factorial (n - 1) * n); c. Add these lines in the recursive section: temp - factorial (n - 1); System.out.println ("Factorial of: " + (n - 1) + " is " + temp); return (temp * n); 3. Rerun the program and note how the recursive calls are built up on the run-time stack and then the values are calculated in reverse order as the run-time stack "unwinds".

Complete the following program to implement the user interface of the preceding exercise. For simplicity, only the units cm, m, and in are supported. Hint: The value of factor1 or factor2 should be the conversion factor from the selected unit to cm. Ex: If the selected unit is in, factor1 is 2.54 because 1 in = 2.54 cm."in java"
Problem: Min Method (Return the Smaller Number) Create a method GetMin(int a, int b), which returns the smaller of two numbers. Write a program, which takes as input three numbers and prints the smallest of them. Use the method GetMin(…), which you have already created. Sample Input and Output Input Output Input Output 123 1 -100-101-102 -102 Hints and Guidelines Define a method GetMin(int a, int b) and implement it, after which invoke it from the main program as shown below. In order to find the minimum of three numbers, first, find the minimum of the first two and then the minimum of the result and the third number: var min = GetMin(GetMin(num1, num2), num3);References: Programming Basics with C#: Comprehensive Introduction to Programming with C#: Book + Video Lessons by Dr. Svetlin Ivanov NakovPaperback

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
