Java programs that are embedded in a Web page.
stand-alone, executable program.
stand-alone Java programs.
Architecturally neutral:
you can use it to write a program that runs on any platform (operating system).
information passed to a method so it can perform its task.
characteristics that define an object as part of a class.
Block comments:
start with a forward slash and an asterisk (/*) and end with an asterisk and a forward slash (*/). Block comments can appear on a line by themselves, on a line before executable code, or on a line after executable code. Block comments can also extend across as many lines as needed.
consists of programming statements that have been compiled into binary format.
in procedural program, invoke a series of procedures to input, manipulate, and output values.
group or collection of objects with common properties.
Comment out:
turn a statement into a comment so the compiler will not execute its command.
Compiler, or interpreter:
program that translates language statements into machine code.
Computer program:
set of instructions that you write to tell a computer what to do.
Console applications:
support character output to a computer screen in a DOS window.
free a program of all errors.
Dialog box:
GUI object resembling a window in which you can place messages you want to display.
refers to the hiding of data and methods within an object.
Executing a statement:
carry it out.
frequently asked questions.
High-level programming language:
allows you to use a vocabulary of reasonable terms, such as "read," "write," or "add," instead of the sequences of on and off switches that perform these tasks.
name of a class or object.
Import statement:
used when you want to access a built-in Java class that is contained in a package.
ability to create classes that share the attributes and methods of existing classes, but with more specific features.
existing object of a class.
developed by Sun Microsystems as an object-oriented language used both for general-purpose business applications and for interactive World Wide Web-based Internet applications.
Java API:
application programming interface, a collection of information about how to use every prewritten Java class.
Java interpreter:
program checks the bytecode and communicates with the operating system, executing the bytecode instructions line-by-line within the Java virtual machine.
Java virtual machine (JVM):
hypothetical (software-based) computer used to run Java.
Javadoc comments:
special case of block comments begin with a forward slash and two asterisks (/**) and end with an asterisk and a forward slash (*/). You can use javadoc comments to generate documentation with a program named javadoc.
Java class allows you to produce dialog boxes.
Line comments:
start with two forward slashes (//) and continue to the end of the current line. Line comments can appear on a line by themselves or at the end of a line following executable code.
Literal string:
series of characters that appear exactly as entered. Any literal string in Java appears between double quotation marks.
executing the various statements and procedures in the correct order to produce the desired results.
Logic error:
occurs when a program compiles successfully but produces an error during execution.
Machine language:
program written in circuitry-level language, as a series of on and off switches.
self-contained block of program code, similar to a procedure.
instances of a class; they are made up of attributes and methods.
Object-oriented programs:
creating classes, creating objects from those classes, and creating applications that use those objects. Thinking in an object-oriented manner involves envisioning program components as objects that are similar to concrete objects in the real world; then, you can manipulate the objects to achieve a desired result.
contains a group of built-in Java classes.
arguments passed to methods.
Pascal casing:
using an uppercase letter to begin an identifier and to start each new word in an identifier.
sending arguments to a method.
describes the feature of languages that allows the same word to be interpreted correctly in different situations based on the context.
Procedural programming:
style of programming in which sets of operations are executed one after another in sequence.
sets of operations performed by a computer program.
set of instructions that you write to tell a computer what to do.
Program comments:
nonexecuting statements that you add to a Java file for the purpose of documentation.
Program statements:
similar to English sentences; they carry out the tasks that programs perform.
Run-time error:
occurs when a program compiles successfully but does not execute.
