For this assignment, you will analyze code that uses the JDBC API to access a database, retrieve data, and compose output based on that data. You will then comment the code to reflect the purpose and expected results of the code.   Download the linked TXT file, and read through the Java™ code carefully.   […]

Deadlock occurs when no processing can occur because two processes that are waiting for each other to finish. For example, imagine that two processes need access to a file or database table row in order to complete, but both processes are attempting to access that resource at the same time. Neither process can complete without […]

For this assignment, you will analyze code that uses a file input stream and a file output stream.   Read through the linked Java™ code.   In a Microsoft® Word document, answer the following questions:   Could this program be run as is? If not, what is it lacking?   Does this program modify the […]

For this assignment, you will analyze Java™ that presents instructional text on the console, accepts user input, and then create a file based on that user input.   Read the linked Java™ code carefully.   Then, answer the following questions in a Microsoft® Word file:   As you run the program in NetBeans the first […]

You work for a company that has different types of customers: domestic, international, business partners, individuals, and so on. It well may be useful for you to “abstract out” all the information that is common to all of your customers, such as name, customer number,   order history, etc., but also keep track of the […]

Data Hiding Data hiding is the way in which programmers implement encapsulation. Java™ programmers use the keywords private and protected to control what data is visible outside of a class; in other words, to control what code can access and manipulate class data.   Read Table 1-2, “Determining Access to Class Members,” in “Java – […]

Databases Accessible via JDBC The purpose of this discussion is to identify the purpose and utility of JDBC to Java™ programmers, including the data formats that JDBC allows Java™ programmers to interact with. Research and discuss the differences between a flat database and a relational database. Does JDBC provide a way for Java™ programmers to […]

Benefits and Drawbacks of Concurrency The purpose of this discussion is to explore concurrency, which refers to threads that run alongside each other during program execution, as opposed to running serially, or one after the other, and to discuss potential drawbacks and problems associated with concurrency.   Java™ provides built-in support for concurrent programming by […]

Data Conversion Accepting input and producing output virtually always requires data conversion. Because Java™ students new to I/O are often surprised at the steps necessary to read data and then put it in a form that can actually be used, the purpose of this discussion is to experiment with data conversion techniques and share the […]
