...Muhammad 1 Mikey Muhammad Date Class Mr.Radev Java Programming and Inheritance As time continues to pass, the world we now live in is dominated by the use of technology. Technology continues to advance, and it seems, as if we can’t function without it. Whether it’s the use of technology in school or work, it is everywhere and you cannot escape it. It is important for us to be able to adapt to it and learn how the new inventions work and function properly. The Internet for example is one of the most important aspects of life today. The Internet allows us to have access to everything, and have endless information at our fingertips, whether it’s through a computer screen or through the use of a cellular device, or even a watch. Some of us choose to only use this amazing tool that has been provided to us, and then some us choose to go more in depth with this tool we call the Internet and want to know how it works. Although it takes millions of programs and concepts and other factors to get the Internet working how it does, the focus of my term paper will be Inheritance in Java. In order to truly understand what the specifics of Java are, you have to start with the totality of the Java program. The Java language could easily be the most difficult to understand because there are so many components to how it works. Java is a programing language and computing platform, which is a huge part of making the Internet work. It was first released by Sun Microsystems in 1995. Without...

...Advanced Programing in Java Umair Javed CS-391 Java Program Development and Execution Steps Java program normally go through five phases. These are 1. 2. 3. 4. 5. Edit, Compile, Load, Verify and Execute We look over all the above mentioned phases in a bit detail. First consider the following figure that summarizes the all phases of a java program. Phase 1 Editor Disk Program is created in the editor and stored on disk. Compiler creates bytecodes and stores them on disk. Phase 2 Compiler Disk Primary Memory Phase 3 Class Loader Class loader puts bytecodes in memory. Disk Primary Memory Phase 4 Bytecode Verifier Bytecode verifier confirms that all bytecodes are valid and do not violate Java’s security restrictions. Phase 5 Primary Memory Interpreter Interpreter reads bytecodes and translates them into a language that the computer can understand, possibly storing data values as the program executes. Umair© 2005, All Rights Reserved -1- TA: Munawar Nadeem Handout 3 Advanced Programing in Java Umair Javed CS-391 Phase 1: Edit Phase 1 consists of editing a file. This is accomplished with an editor program. The programmer types a java program using the editor like notepad, and make corrections if necessary. When the programmer specifies that the file in the editor should be saved, the program is stored on a secondary storage device such as a disk. Java program file name ends with a .java extension. On Windows...

...Encapsulation is whereby variables, functions are protected from being accessed by other codes outside the class. This helps manage the code being protected and has least if any impact on other parts of a program if change was to occur in the protected code. Encapsulation is important in java due to its flexibility and it is easy to change with new requirement, the class has total control over what is stored in its field, one part of the code can be changed and the rest of the would not be affected and also encapsulation is useful since it is easy to maintain. Both the mutator and accessor method are used to enforce data encapsulation where their jobs is returning and setting the value state of an object. Mutator method is used to set the private field value. It is denoted by using set at the beginning of the method name. Example of a mutator method would be public void setSchool (String school). Accessor method is used to return the private field value. It is denoted by using get at the beginning of the method name. An example of accessor method would be public String getFirstName () Implicit parameter is the object on which the method is invoked whereas explicit parameter is the parameter of the method other than the object the method is invoking and is enclosed in a parentheses. To access an explicit parameter variable inside the method refer the parameter variable by its name. To illustrate what is an implicit and explicit parameter we use the following code: Person...

...They should not be abolished because: * Exams make people better at the subject * content tested in exams are random, so people study everything * since it affects grades, people study harder * there is competition, people study harder * They help the teacher to know what material the students have not mastered and need to study further * They give people important practice in dealing with stress, which can help later on with life's challenges. * The examination system has its own benefits. It's like a self-test to see where we are and how good we fare in something that we do. The purpose of exam has always been a test to let us, human beings, to know our limits and our standards. * Frankly speaking, who can put his/her hand on their heart and say that they would have learned the lessons regarding different subjects themselves if the present examination system were not there and didn't made the students to learn and understand the topics dealing with different subjects to perform at the end of the year. The ANSWER would be No, They wouldn't have. Exams should not be abolished. Until a better form of demonstrating knowledge comes along, exams must remain in place. In the world of occupations, exams are especially useful. A given state, county, town, or other regionally-governed area requires certain knowledge for certain occupations. The most effective way of evaluating an individual's knowledge of a given topic is the use of exams. These...

...Question Compile the two test files (BankAccount.java first and then Program2.java second). Execute Program2 with the following inputs: starting balance - $500 (don't enter the dollar sign) monthly interest rate - 0.00125 (this is a 1.5% annual rate) monthly pay - $1000 (don't enter the dollar sign) withdrawal amount - $900 (don't enter the dollar sign) Verify that you earn $0.75 in interest and have an ending balance at the end of the month of $600.75. Then modify the BankAccount class's constructor method to create a BankAccount object which stores a monthly interest when the user inputs an annual interest rate of the format "nnn.nn" (i.e. 1.5). Note that the BankAccount constructor stored a monthly interest rate for the BankAccount object's instance field originally, but the user had to convert the annual rate to a monthly rate (i.e. 1.5 to 0.00125). Then modify the Program2 driver class to prompt the user for an annual interest rate. Recompile both classes and execute the modified Program2 driver class again, this time with following inputs: starting balance - $500 (don't enter the dollar sign) annual interest rate - 1.5 monthly pay - $1000 (don't enter the dollar sign) withdrawal amount - $900 (don't enter the dollar sign) Verify that you still earn $0.75 in interest and still have an ending balance at the end of the month of $600.75 as you did with the original code.
