J2ME Interview Questions and Answers
What is JDBC for CDC/FP ?
The JDBC Optional Package for CDC/Foundation Profile (JDBCOP
for CDC/FP) is an API that enables mobile Java
applications to communicate with relational database
servers using a subset of J2SE's Java Database
Connectivity. This optional package is a strict subset
of JDBC 3.0 that excludes some of JDBC's advanced and
server-oriented features, such as pooled connections and
array types. It's meant for use with the Foundation
Profile or its supersets.
What is JSR
Java Specification Request (JSR) is the actual
description of proposed and final specifications for the
Java platform. JSRs are reviewed by the JCP and the
public before a final release of a specification is
made.
What is KittyHawk
KittyHawk is a set of APIs used by LG Telecom on its
IBook and p520 devices. KittyHawk is based on CLDC. It
is conceptually similar to MIDP but the two APIs are
incompatible.
What is KJava
KJava is an outdated term for J2ME. It comes from an
early package of Java software for PalmOS, released at
the 2000 JavaOne show. The classes for that release were
packaged in the com.sun.kjava package.
What is kSOAP
kSOAP is a SOAP API suitable for the J2ME, based on kXML.
What is kXML
The kXML project provides a small footprint XML parser
that can be used with J2ME.
What is KVM
The KVM is a compact Java virtual machine (JVM) that is
designed for small devices. It supports a subset of the
features of the JVM. For example, the KVM does not
support floating-point operations and object
finalization. The CLDC specifies use of the KVM.
According to folklore, the 'K' in KVM stands for
kilobyte, signifying that the KVM runs in kilobytes of
memory as opposed to megabytes.
What is LAN
A Local Area Network (LAN) is a group of devices
connected with various communications technologies in a
small geographic area. Ethernet is the most widely-used
LAN technology. Communication on a LAN can either be
with Peer-to-Peer devices or Client-Server devices.
What is LCDUI
LCDUI is a shorthand way of referring to the MIDP user
interface APIs, contained in the
javax.microedition.lcdui package. Strictly speaking,
LCDUI stands for Liquid Crystal Display User Interface.
It's a user interface toolkit for small device screens
which are commonly LCD screens.
What is MExE
The Mobile Execution Environment (MExE) is a
specification created by the 3GPP which details an
applicatio n environment for next generation mobile
devices. MExE consists of a variety of technologies
including WAP, J2ME, CLDC and MIDP.
What is MIDlet
A MIDlet is an application written for MIDP. MIDlet
applications are subclasses of the
javax.microedition.midlet.MIDlet class that is defined
by MIDP.
What is MIDlet suite
MIDlets are packaged and distributed as MIDlet suites. A
MIDlet suite can contain one or more MIDlets. The MIDlet
suite consists of two files, an application descriptor
file with a .jad extension and an archive file with a
.jar file. The descriptor lists the archive file name,
the names and class names for each MIDlet in the suite,
and other information. The archive file contains the
MIDlet classes and resource files.
What is MIDP
The Mobile Information Device Profile (MIDP) is a
specification for a J2ME profile. It is layered on top
of CLDC and adds APIs for application life cycle, user
interface, networking, and persistent storage.
What is MIDP-NG
The Next Generation MIDP specification is currently
under development by the Java Community Process. Planned
improvements include XML parsing and cryptographic
support.
What is Mobitex
Mobitex is a packet-switched, narrowband PCS network,
designed for wide-area wireless data communications. It
was developed in 1984 by Eritel, an Ericsson subsidiary,
a nd there are now over 30 Mobitex networks in operation
worldwide.
