Java Programming

Other than throwing an exception or a run-time library error, or forcibly terminating the process, there is only one way of exiting a program; you return from the entry point function, usually main(), provided by the library, or from winmain(), if you are using Windows.

A High level language is a language like C, Pascal, Fortran. To convert, the easiest way is to use a compiler.

A compiler will take the instructions written in a high level language and convert them into machine code which is the specific instruction set for that type of computer. Assembly language is just a human readable form of a machine code which is how the designers of the computer instruction set made it work.

A disassembler will show the assembly language from machine code. But the compiler usually includes a lot of optimisations from a the high level language and will not often generate very simple assembly.

I guess you want to talk about the garbage collector feature that Java has.

The garbage collector is an automated program that the Java virtual machine would run once in a while. This program would clean up unused memory to ensure that there is enough memory available for the programs.

you can invoke the garbage collector by calling the system.gc() method but this does not guarantee an invocation of the garbage collector. the JVM may or may not call the GC when we invoke it...

Any spaces, tabs, or blank lines, that don't contain actual commands. Whitespace is used to separate keywords, variables, etc. Whether you put a single space, several spaces, an ENTER, or some other combination is irrelevant for the compiler, but it is still extremely important to use proper indentation, because otherwise, the program will be very confusing for a human to read.

The basic algorithm for a bubble sort requires a boolean indicator. As the program cycles through the array to be sorted, it steps by one and compares n and n+1. If n+1 is greater than n, then they are swapped, the boolean indicator is set to false and the comparator increments by one. Once the comparator makes a complete cycle through without the indicator flagging to false, the array is sorted.

String data type allows unlimited character intput

Java programming is very important because it can help you make web applications. Thanks for one reason but I need more reasons for my opinion piece!

Conversations with Inanimate Objects was created in 2005.

Java compiler available on multiple platforms, the class files it generates are platform-independent.

Anytime you download software the will be executed on your computer, you face risks. Make sure you know the source of the software. Then you can judge whether or not the level of risk is acceptable vs. the potential benefits of the software.

Function oriented design breaks a system down into one or more named functions which transform their inputs to produce an output, such that the output of one function may be used as input to another function. In addition, the system also typically provides a global state which any function may operate upon.

In order for the "system of functions" to operate there has to be single point of entry which is typically provided by the system's global main function. The inputs for this particular function are derived from the command line used to invoke the system while the output is an integer typically used to indicate a system-defined error (with the value 0 usually indicating no error). Typically, the global main function decodes the command line parameters to determine what work is to be performed (if any) and to delegate that work to an appropriate function.

Although a single function can perform a significant amount of work, complex systems are much easier to understand when the work is divided amongst many smaller, simpler functions. When the functions are appropriately named, code becomes largely self-documenting, with the low-level implementation details largely hidden from the user.

JDBC stands for Java Data Base Connectivity. As the name suggests the package is reposnisble for database connectivity. It is a standard API defined for database access.

Yes. An interface in essence is a java class and so you can use the term interface class. But, using the term class along with the term interface can cause ambiguity or misunderstandings among novice java developers. So, using the term "Interface" along would suffice to refer to a type of class which is the "Interface"

Its good practice to always use the most recent version of the respective software system you are trying to run. In the case of Java that means you want to run Java JRE 1.6 for pretty much everything. You also may want to consider removing the older versions of Java as they may conflict with the newer version.

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

System.out.println("Enter any number");

int n=Integer.parseInt(br.readLine());

There are classes in java.awt Menu and MenuItem which are used for the creation of menus and they can be put inside Frame.
