image mapAn image divided into logical areas, each of which has a hot spot.
immutable objectAn object whose state may not be changed. Objects of the String class are immutable, for instance - their length and contents are fixed once created.
imperative programmingThe style of programming usually associated with languages such as C, Fortran, Pascal and so on.
impersonationThe ability of a thread to run in the security context of a security principal different from the security principal that started the process.
implementsA Java keyword included in the class declaration to specify any interfaces that are implemented by the current class.
implements clauseThat part of of a class header that indicates which interfaces are implemented by the class. A class may implement more than one interface.
implicit type conversionType conversion that does not require a cast. Implicit type conversions typically do not involve any loss of information.
ImportData brought into an environment or application which has been exported from another environment or application.
import statementA statement that makes the names of one or more classes or interfaces available in a different package from the one in which they are defined.
inconsistent stateA state that an object should not be in. A class needs to be carefully designed in order to ensure that none of its instances can get into an inconsistent…
increment operatorAn operator (++) that adds one to its operand. It has two forms: pre-increment (++x) and post-increment (x++).
indirect recursionRecursion that results from method Y calling method X, when an existing call from X to Y is still in progress.
infinite loopA loop whose termination test never evaluates to false. Sometimes this is a deliberate act on the part of the programmer, using a construct such as…
infinite recursionRecursion that does not terminate. This can result from any of direct recursion, indirect recursion or mutual recursion.
information hidingThe practice of ensuring that only as much information is revealed about the implementation of a class as is strictly required.
inheritanceThe transmission of genes and phenotypes from generation to generation.
inheritance hierarchyThe relationship between super classes and sub classes is known as an inheritance hierarchy.
