Diff between out.write and out.print

They have the seek-read-and-maybe change-without-recopying-everything functionality you describe. However I don't know if there's a way to specify a particular sector - can this be represented by a file name and thus a File object? This may be too OS-specific. You might need to use JNI to connect to a C function

What Is the Console? The Console is a window of the operating system through which users can interact with system programs of the operating system or with other console applications. The interaction consists of text input from the standard input usually keyboard or text display on the standard output usually on the computer screen.

Input and Output

These actions are also known as input-output operations. The text written on the console brings some information and is a sequence of characters sent by one or more programs. For each console application the operating system connects input and output devices. By default these are the keyboard and the screen but they can be redirected to a file or other devices.

Communication between the User and diff between out.write and out.print Program A lot of programs communicate in some way with the user. This is necessary for the user in order to give instructions to them.

Modern communication methods are many and various: As we mentioned one of the tools for communication between programs and users is the console, which is becoming less and less used.

When to Use the Console? In some cases the console remains an irreplaceable tool for communication with the user. One of these cases is when writing small and simple programs where it is necessary to focus the attention on the specific problem to be solved, rather than the elegant representation of the result to the user.

Then a simple solution is used for entering or printing a result, such as input-output console. Another use case is when we want to test a small piece of code for a larger application. Due to simplicity of the operation of the console application we can isolate this part of the code easily and comfortably without having to go through a complex user interface and a number of screens to get to the desired code for testing.

How to Launch the Console? Each operating system has its own way to launch the console. On Windows for example, it can be done in the following way: When starting the console the home directory of the current user in this case the username is nakov is used as a current directory and this is displayed as a guide for the user.

Console can be launched through pressing the Start button and typing "cmd" in the search box and pressing [Enter] on Windows Vista, Windows 7 and later. For simplified visualization of the results from now on in this chapter instead of a console screenshot we will use the form: Results from console More about Consoles The system console is the black window shown above which displays text information.

It can display text strings and has a cursor, which moves to the right after each character is printed. After the cursor passes through the last column of the console usually it has 80 columnsit moves to the beginning of the next line. If the cursor passes through the last line, the console scrolls its content upwards and shows a new empty line below the last line.

Programs in Windows can be console-based, desktop-based, Web-based and other.

The console-based programs use the console for their input and output. The desktop-based programs use graphical user interface GUI. The Web-based programs have Web-based user interface.

In this book we will write console-based programs almost all the time, so their input will be read from the keyboard and their output will be printed in the console. Some console-based programs expect the users to enter text, numbers and other data, and this is usually done through the keyboard.

The console in Windows is often associated with the system command interpreter, also called the "Command Prompt" or "shell" or which is a console-based program in the operating system, which provides access to system commands as well as a wide range of programs, which are part of the operating system or are additionally installed to it.

The word "shell" means "wrap" and has a meaning of a wrapper between the user and the inside of the operating system. The so called operating system "shells" can be split into two main categories according to the type of interface they can provide to the operating system: For both types the main purpose of the shell is to run other programs with which the user works although most of the interpreters also support some advanced features such as the opportunity to examine the content of directories with files.

Each operating system has its own command interpreter that has its own commands. For example, when starting Windows console, we run the so-called Windows command interpreter in it cmd. For example, the command dir shows the files in the current directory:A Computer Science portal for geeks. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview .

What are the differences between a while loop and a do-while loop? Convert the following while loop into a do-while loop. Convert the following while loop into a do-while loop. A Fortran program reads from standard input or from a file using the read statement, and it can write to standard output using the print statement.

With the write statement one can write to standard output or to a file. Before writing to a file, the file must be opened and assigned a unit number with which the programmer may reference the file.

The only difference between the get function and the >> operator is that get reads the first character typed, even if it is a space, tab, or the [Enter] key.
