Java 2 chapter 10
exception
in object-oriented terminology, an unexpected or error condition.
runtime exception
an unplanned exception that occurs during a program’s execution; used more specifically to describe a member of the RuntimeException class.
stack trace history list
a list that displays all the methods that were called during program execution.
Exception handling
an object-oriented technique for managing or resolving errors.
stack trace
a list that displays all the methods that were called during program execution.
crash
a premature, unexpected, and inelegant end to a program.
mission critical
any crucial process in an organization.
Fault-tolerant
describes applications that are designed so that they continue to operate, possibly at a reduced level, when some part of the system fails.
catch block
segment of code that can handle an exception that might be thrown by the try block that precedes it.
Robustness
describes the degree to which a system is resilient to stress, maintaining correct functioning.
try block
a block of code that a programmer acknowledges might generate an exception.
throw statement
a statement that sends an Exception out of a block or a method so it can be handled elsewhere.
finally block
a block of code that executes at the end of a try...catch sequence.
catch or specify requirement
the Java rule that checked exceptions require catching or declaration.
Unchecked exceptions
exceptions that cannot reasonably be expected to be recovered from while a program is executing. Contrast with checked exceptions.
Checked exceptions
exceptions that a programmer should plan for and from which a program should be able to recover. Contrast with unchecked exceptions.
exception specification
the practice of using the keyword throws followed by an Exception type in the method header; required when a method throws a checked Exception that it will not catch but will be caught by a different method.
throws clause
an exception specification in a method header.
Syntactic sugar
describes aspects of a computer language that make it “sweeter,” or easier, for programmers to use.
call stack
the memory location where the computer stores the list of memory locations to which the system must return when methods end.
assertion
a Java language feature that can help detect logic errors and debug a program.
syntactic salt
describes a language feature designed to make it harder to write bad code.
virtual keyboard
a computer keyboard that appears on the screen. A user operates it by using a mouse to point to and click keys; if the computer has a touch screen, the user touches keys with a finger or stylus.
