Activity 2.2: Operators, Operations & Consta In this activity, you will use your knowledge of both Chapter 1 and 2 materials to analyze and understand the given code. Make sure to finish the activity without using IDE first. You can use IDE after hand tracing the code. Content Learning Objectives After completing this activity, students should: Get familiar with mathematical and relational operators Learn about variables, data types, and data types with operators Get familiar with writing programs that solve simple mathematical problems. Process Skills Goals After completing this activity, students should make progress towards: Analyzing skills and ability to hand trace code Section 1: Hand Tracing Code Check Point: 30 Minutes A program is given to you below. Go through each line and describe what it does by writing notes in the margins. Add necessary data type casting to the lines (The program below does not compile otherwise). Next, fill the table in page #2, with the answer to the corresponding inline comment question as well as the corresponding inputs for dx and dy. import java.utusanne public class Basiscalculator public static void main(stringil xos Scanner input new Scanner system, ain) Hatan Antxi double , dx, float Swalewe dy Input Dexinouble BOROWE Prompt the user for Svatebut.print 'Ent dx input nextBoybi extrouble 0 No OS Ub Systest. eut Ra y ti He putpuente dz = dx + dy 22 Xy Sat 2 NONNNNN 279 the out n/ana they the sail Vous ne shell without SUERE Line #18 Line #20 Line #26 Line 28 Line 131 Ling #29 BUV 78 words O NLINE 2 Line #18 Line #20 Line #26 Line #28 Line #29 Line #31 3.456 3.56 712345678 0.12345678 776 words English (United States) JAN POTES 210.00 4)@ 3 22 Section 2: Analyzing and Completing Code Check Point: 15 Minutes Parts of a program are given to you below.
