Pipe: It is a linkage between the two program components. One component responds as a source of data, and writes into the pipe. The second components act as a receiver (that is, sink) for the data and
Define the term Peripheral devices: It is the devices attached to a computer, like disk drives, printers, mice, and so forth.
Peer: It is a term employed of the Abstract Windowing Toolkit (AWT) to refer to the underlying classes which give the platform-specific implementation of the component classes.
Pattern: It is a recurring theme in class usage or design. Interfaces like Iterator encapsulate a pattern of admission to the items in a collection, whereas freeing the client from the requirement to
Parsing: Generally applied to the action of a compiler in examining a program source file for syntax errors. This is too employed more broadly to mean the analysis of the structure of input.
Parallel programming: It is a style of programming in which statements are not essentially executed in an ordered series but in parallel. The parallel programming languages make it simpler to produce
Package declaration: It is a declaration employed to name a package. This should be the first item in the source file, preceding any import statements. For example, package java.la
Package: The named grouping of classes and interfaces which gives a package namespace. Classes, interfaces and class members devoid of an explicit public, protected or private access modifier {access!
Overriding for restriction: It is a form of method overriding in which the sub-class version of a method calls the super-class version first of all and then employs or manipulates the outcome or conse
Overriding for chaining: It is a form of method overriding in which the sub-class version of a method verifies to see whether it can react to the message on its own and just calls the super-class vers
Overriding for breadth: It is a form of method overriding in which the sub-class version of a technique implements its own behavior within the context of attributes and behavior of the sub-class and t
Out of scope: It is a variable is in scope as long as the program's flow of control is in the variable's defining block. Or else, this is out of scope.
Out-of-bounds value: It is a redundant value employed to point out that a different action from the norm is needed at some point. The read technique of InputStream returns -1 to point out that the end

Octal: Number representation of octal is base 8. In base 8, simply the digits 0 to 7 are employed. Digit positions symbolize successive powers of 8.
Object serialization: The writing of an object's contents in such a manner that its state can be restored, either at a later time, or in a different procedure. This can be employed to store objects be
Object reference: It is a reference to an object. Languages other than Java employ terms like pointer or address or. It is significant to keep the difference clear between an object and its reference.
Object-oriented language: Programming languages like Java and C++ which permit the solution to a trouble to be stated in terms of objects that belong to the classes.
Object construction: The creation of an object, generally through the new operator. Whenever an object is formed, a suitable constructor from its class is summoned.
Object: It is an instance of a particular class. In common, any number of objects might be constructed from a class definition. The class to which an object belongs states the common characteristics o
