Exceptions in java is the way of indicating the occurrence of abnormal
condition in the program. Actually, these are objects that are thrown when
program encounters any problem executing the program further.
Java integer to string
Many times we need to convert a number to a string to be able to operate
on the value in its string form. Converting numeric values to Strings with
Java is very easy.
Java Integer class
Java provides wrapper classes corresponding to each primitive data types
in its "lang" package. These classes represent the primitive values
as objects offers utility methods to manipulate the values.
Java installation
Java comes in different editions JSE (Java Standard Edition), JEE (Java
Enterprise Edition), JME (Java Micro Edition). Beginners should try start
java programming with JSE. For this, you need to download, install and
configure the JSE development environment.
java inetaddress
This class of java in "java.net" represents an Internet Protocol
(IP) address. InetAddress class is used to create and manipulate IP objects.
It does not have a public constructor.
Java if else
The if-else statement is one of the widely used control flow statements
while programming. It lets the program execute a set of statements enclosed
within the "if" block only if the certain condition evaluates to
true otherwise program executes statements of "else" block. So it
provides the facility to the programmer to handle the condition based
programming.
Java Naming
and Directory Interface
The Java Naming and Directory Interface (JNDI) is
a directory service based API to allow the clients to discover and lookup data and objects via a
name.
Java Remote Method Invocation
The Java Remote Method Invocation API, is application programming interface that
performs the object
equivalent to remote procedure calls. There are two common implementations of
the API.
Java Remote Interface
The Remote
interface identifies
interfaces whose methods may be invoked remotely from a non-local virtual
machine. Any remote object must directly or indirectly implement this interface.
Include directive vs Include Action
Include directive (<%@ include %>)
includes file into the JSP page at compile time. Include directive should be
used if the included code is in the same page.
Java for Internet Explorer
In this article we are taking Windows as the operating
system and web browser as Internet Explorer 7.
JSP Implicit Objects
Implicit objects in jsp are the objects that are
created by the container automatically, we do not need to create them
explicitly. Since these objects are created automatically therefore these are
known as the implicit objects.
Introspection
Introspection is the automatic process that analyzes
the design pattern of a bean in order to reveal bean's properties, events,
and methods. This process is used to control publishing and discovery of bean
operations and properties.
Inheritance
In OOPs, these concepts are implemented through a class definition and achieved
through the object creation process, programmatically.
JSP import
An import is the attribute of the page
directive in JSP that imports the java packages
and it's classes whenever required for the JSP page.
More than one java packages and classes can also be imported by separating
with comma (,).
JSP include
A JSP page can include page
fragments from other files to form the complete response. There are two
include mechanisms: the include directive and the include action.
The if Keyword
The if is a keyword, which is used to
perform the selection statement. It is used to execute the statements after
evaluating the condition specified in it as true. When the condition is true,
the code in the "if" block is executed.
The implement keyword
In java programming language, the keyword implement
specifies that the given class
implements an interface. Keywords
are basically reserved words which have specific meaning relevant to a compiler.
The import keyword
The import statement make available one or all the
classes in a package to the current source file. Keywords
are basically reserved words which have specific meaning relevant to a compiler.
The instanceof keyword
The keyword instanceOf in java
programming language is a boolean operator that is used to test whether an object is
of an specified type or not and returns the value accordingly. Keywords
are basically reserved words which have specific meaning relevant to a compiler.
The interface keyword
In java programming language the keyword interface
in java is used to declare and define an interface. Keywords
are basically reserved words which have specific meaning relevant to a compiler.
The int keyword
The int is a keyword in java that is used to define
32-bit signed integer (primitive type) values. Keywords
are basically reserved words which have specific meaning relevant to a compiler.
Inner Classes In Java
Inner classes provides an elegant and powerful feature to the Java
programming language.
