Document Content and Description Below

Informatics 1B – Project Total = 60 Question 1 (20 marks) Refer to the operations below: Add (10 + 5) Add (4+8) Add (7*2) Add (90 – 3) Print list Print peek Remove an item from the list ... Print list 1.1 Implement the operations above into a Queue structure called q1. (10) 1.2 Implement the operations above into a Stack structure called s1. (10) Question 2 (20 marks) Create a complete java program called Week_Report. The program must include two array structures, a string array called DaysOfWeek and a double array called Temp_Values. Store in the DaysOfWeek array the following values (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday). Store in the Temp_Values array the following (23.5, 34.0, 20.9, 45.7, 29.3, 34.5, 32.5). Using a for loop structure output the values for the two arrays. Day of the Week Temperature Values Monday 23.5 Tuesday 34.0 Wednesday 20.9 Thursday 45.7 Friday 29.3 Saturday 34.5 Sunday 32.5 Question 3 (20 marks) Create an object called Circle. Declare the following integer variables for the object Circle, radius, diameter, and pi is declared as double. Create the following for the Circle object: ● Implicit constructor (default constructor) ● Void method Calculate (double pi, int radius) to calculate the area of the Circle object. The method must include a system.out statement that displays the area value. Use the following formula to calculate area of the circle: Area = pi * (r * r) Your program includes a main class called Shape with a reference c1 to the Circle object. Pass the following values to the object Circle: radius = 4 diameter = 8 pi = 3.14 Include output statements to view the values passed to the object Circle [Show More]
