A virtual machine simplifies the task of writing a distributed application as it provides followings;
Primitive type: Java's eight standard non-class types are the primitive types as: Boolean, byte, char, float, int, double, long and short.
Program counter: A program counter is an integral portion of a computer's Central Processing Unit. It includes a reference to the memory address of the subsequent instruction to be fetched, ready to be executed throughout the next fetch-execute cycle.
What is an Unary operator: It is an operator which takes a single operand. Java's unary operators are as -, +, !, !, ++ and --.
Assembler: The program employed to translate a program which is written in assembly language into the binary form of a specific instruction set.
Scalability of program model checkers such as JPF encompasses two aspects: How large a program can be model checked, and Once a defect has been detected, how readily meaningful debugging informati
Swapping: An {operating system} is frequently able to run programs which need more memory than is physically accessible on the host system. In order to do this, the complete memory needed is broken down into smaller pieces that are swapped in whenever
Modeling Language: The modeling language used for SPIN is called Promela (Process Meta Language). In fact, the name SPIN stands for Simple Promela Interpreter. Promela is a powerful C-like specification language with a variety of synchronization primi
"this" pointer: In C++ uses a unique keyword called "this" to represent a object that
Fully evaluating operator: An operator which computes all of its arguments to generate an outcome. Standard arithmetic operators, like +, are totally evaluating. In contrary, some Boolean operators, like &&, are short-circuit operators.
Use of setjmp() and longjmp(): In C/C++, setjmp() saves the contents of the registers at a particular state in the program and longjmp() will restore that state later. In this way, longjmp() “returns” to the state of the program when setjm
