Assignment 1 – Loops and Arrays UNSW Blogs Home UNSW Wikispaces UNSW Website MyUNSW RSS COMP1400 – Programming for Designers Class announcements for Programming for Designers Assignment 1 – Loops and Arrays Posted by Claude on August 15th, 2013 · Assignments Due: 11:59pm Sunday 1 September (i.e. the end of week 5) This assignment is about loops arrays. You will write three methods to manipulate arrays. The first two are easy. The third one will require more thought about the design. You will submit the assignment using the CSE give system (see below). Download the BlueJ project, Assignment1.zip. It contains three methods. You have to write the code that goes inside them. Question 1 The first method finds the average of the elements of an integer array: public double average(int[] data) That is, given an integer array, data, calculate what the average of its elements are and return the average value. For example, the average of {1, 3, 2, 5, 8} is 3.8. Question 2 The second method is: public int countInRange(int[] data, int lo, int hi) For this, you have to count the number of elements of the array, data, that lie in the range lo to hi inclusive, and return the count. For example, if data is the array {1, 3, 2, 5, 8} then the call countInRange(data, 2, 5) should return 3 because there are three elements, 3, 2 and 5 that lie in the range 2 .. 5. Question 3 The third method, arrayAdd, takes two arrays as parameters and returns a new array that is the sum of the first two. public int[] arrayAdd(int[] R1, int[] R2) The addition of two arrays yields an array whose elements are the sum of the corresponding elements in the parameter arrays, i.e. R1[0] + R2[0], R1[1] + R2[1], R1[2] + R2[2], .... Submission instructions You will submit your assignment to the Give automated marked system. From within your assignment 1 BlueJ project, select Project -> Create Jar File… In the Dialog Box that appears: Set “Main Class” to none Ensure “Include Source” is checked Leave “Include Bluej project files” unchecked Press “Continue” Save the filename as “Assignment1.jar” Open a web browser and go to the give web site Log-in with you Z-Pass Either enter “COMP1400″ in for the course, or select COMP1400 from the drop down menu and press “Search for Assignments”. Note INFSi1609/2609 students may need to enter “COMP1400″ instead of selecting the course form the dropdown Select “assignment1″ from the next drop down menu and press “Upload my Assignment” Accept the student declaration Press “Choose File” and select the “Assignment1.jar” file that you saved in step 4 Press “Submit my Files” Wait for the page to completely load. Then carefully read the output. If the assignment is successful you should see the following lines: ================================================
