Java programming ii | Computer Science homework help
You have been asked by your manager to create a user-friendly application that will present a survey to your customers. The application will compile and analyze the results entered by the survey respondents. You will deliver your working application with a Design Document and test results.
Upon completing all functional and design requirements, submit the following:
- Design document that has UML Class Diagrams to document your design of your Survey and SurveyConductor classes.
- UML Sequence Diagram that documents the design of your SurveyConductor application class.
- Screenshots showing results of testing
- Update your Survey class based on feedback and lessons learned in all Phases of this course. Perfect your code and all comments to all necessary areas to describe what is happening at that point of your code.
- Zipped NetBeans project of the application that correctly meets all stated design and functional requirements.
Code should be well commented. Appropriate use of control structures should be used. Logic should be sound and correct.
A design document should be submitted that contains:
- UML Class and Sequence Diagrams using proper UML notation.
- Pseudocode for the SurveyConductor application.
- Pseudocode for the Survey class methods.
- Logic for error checking to validate the response is between 1 and 5 should be included in the Pseudocode.
- Screenshots showing your application runs. Document each screenshot with a caption that explains the test data entered and the resulting application behavior/output.
True/False competency exam:
The second part of the Key assignment is a competency test that will test your knowledge on fundamental data types, control structures, classes, objects, and methods. If you do not pass this competency exam, you will not be able to proceed to IT251.
- Declaring more than one method with the same name but different sets of parameters is called method overloading.
- You cannot overload a constructor.
- Given a method with the signature:
public void numberCruncher(int num1, int num2, String name)
an example call to this method could be:
myNumberCrunch.numberCruncher(“Fred”, 3, 5)
- The + operator can be used in string concatenation.
- A static method can be used even if no objects of the class have been instantiated.
- A class or static variable should be used when all objects of a class must use the same copy of the variable.
- If packages are used, the package declaration should come directly after any import declarations in a java source file.
- The private access modifier can control the access to variables and methods of a class.
- An accessor is another term for a set method.
- Arrays have to hold the values of the same type.
- The first index of an array is index zero.
- The following code creates an array, b, with 3 columns and 2 rows:
int b = new int;
- Given an array called x, you can access the 5th element in array x by the following code:
x; //reference the 5th element in an array
- Nested for loops are commonly used to display the contents of 2-dimensional arrays.
- The enhanced “for” statement will iterate through the elements of an array.
- Given array ‘y’ that holds values of type int, the following code will set the 5th element of the array to 6:
Y = 5;
- A list of method parameters are separated by semicolons.
- A method can return at most one value.
- Class Math has several static methods.
- The Java Application Programming Interface is a Java class library with thousands of predefined classes.
