  2. Infinite loop - Wikipedia

    en.wikipedia.org/wiki/Infinite_loop

    As long as the system is responsive, infinite loops can often be interrupted by sending a signal to the process (such as SIGINT in Unix), or an interrupt to the processor, causing the current process to be aborted. This can be done in a task manager, in a terminal with the Control-C command, [9] or by using the kill command or system call.

  3. Standard streams - Wikipedia

    en.wikipedia.org/wiki/Standard_streams

    On POSIX systems, the file descriptor for standard input is 0 (zero); the POSIX <unistd.h> definition is STDIN_FILENO; the corresponding C <stdio.h> abstraction is provided via the FILE* stdin global variable. Similarly, the global C++ std::cin variable of type <iostream> provides an abstraction via C++ streams.

    en.wikipedia.org/wiki/List_of_Java_keywords

    The long keyword is used to declare a variable that can hold a 64-bit signed two's complement integer. [5] [6] This keyword is also used to declare that a method returns a value of the primitive type long. [7] [8] native Used in method declarations to specify that the method is not implemented in the same Java source file, but rather in another ...

    A snippet of Java code with keywords highlighted in bold blue font. The syntax of Java is the set of rules defining how a Java program is written and interpreted.. The syntax is mostly derived from C and C++.

  6. Java Class Library - Wikipedia

    en.wikipedia.org/wiki/Java_Class_Library

    The Java Class Library (JCL) is a set of dynamically loadable libraries that Java Virtual Machine (JVM) languages can call at run time. Because the Java Platform is not dependent on a specific operating system , applications cannot rely on any of the platform-native libraries.

  7. Windows File Manager - Wikipedia

    en.wikipedia.org/wiki/Windows_File_Manager

    The program's interface showed a list of directories on the left hand panel, and a list of the current directory's contents on the right hand panel. File Manager allowed a user to create, rename, move, print, copy, search for, and delete files and directories, as well as to set permissions such as archive, read-only, hidden or system, and to associate file types with programs.

  8. write (system call) - Wikipedia

    en.wikipedia.org/wiki/Write_(system_call)

    This is the primary way to output data from a program by directly using a system call. The destination is identified by a numeric code. The data to be written, for instance a piece of text, is defined by a pointer and a size, given in number of bytes. write thus takes three arguments: The file code (file descriptor or fd).

  9. Java performance - Wikipedia

    en.wikipedia.org/wiki/Java_performance

    Benchmarks often measure performance for small numerically intensive programs. In some rare real-life programs, Java out-performs C. One example is the benchmark of Jake2 (a clone of Quake II written in Java by translating the original GPL C code). The Java 5.0 version performs better in some hardware configurations than its C counterpart. [42]
