What is a MIDlet in j2me?
MIDlets are applications created using the MIDP specification and are designed to be executed on devices with limited resources.
What is the meaning of MIDlet file?
• A MIDlet is a java application that uses MIDP and CLDC to be. run on a mobile device. • A MIDlet suite is one or more MIDlets packaged together using. a Java Archive (JAR) file.
What is MIDlet life cycle?
The MIDlet lifecycle is the fundamental for creation of any MIDlet. The lifecycle includes the execution states such as creation, start, pause and exiting operations and a set of valid transitions. To manage the downloading and lifecycle of MIDlets, there is software by name Application Management Software.
What is the full form of J2ME?
J2ME (Java 2 Platform, Micro Edition) is a technology that allows programmers to use the Java programming language and related tools to develop programs for mobile wireless information devices such as cellular phones and personal digital assistants (PDAs).
What are the various languages used for the MIDlet programming?
With either WAP or MIDP, the Java programming language plays an important role. In WAP, Java Servlets and Java Server Pages (JSPs) can be used to generate Wireless Markup Language (WML) pages dynamically, and in MIDP, applications (also called MIDlets) are written in the Java programing language.
What is J2ME and uses?

What is J2ME RMI profile?
The RMI Profile is a J2ME profile specification designed to support Java’s Remote Method Invocation (RMI) distributed object system. Devices implementing the RMI Profile will be able to interoperate via RMI with other Java devices, including Java 2, Standard Edition.
What are the J2ME components?
From a high-level view, J2ME defines the following components:
- A series of Java virtual machines, each for use on different types of small devices, each with different requirements.
- A group of libraries and APIs that can be run under each of the virtual machines; these are known as configurations and profiles.
What is J2EE and J2SE?
J2SE project is for building standalone applications like swing, applets apps etc. J2EE (changed to Java EE) is the edition of the Java 2 platform targeted at developing multi-tier enterprise applications. J2EE consists of a set of specifications, APIs and technologies defining enterprise application development.
What is a J2ME emulator?
The J2ME Wireless Toolkit emulator, for example, is a concept emulator that can be used to represent a variety of MIDP devices. A real-life emulator is designed to mimic the appearance and behavior of an actual device. Such an emulator may run some or all of the binary code that runs on the device itself.
What is the J2ME Wireless Toolkit?
The J2ME Wireless Toolkit is a versatile tool for MIDlet development. The 1.0.4 version supports MIDP 1.0 and includes six emulators. Except for PalmOS_Device, all the emulators appear to be different skins based on the same MIDP implementation.
How many emulators are there in the 1 4 version?
The 1.0.4 version supports MIDP 1.0 and includes six emulators. Except for PalmOS_Device, all the emulators appear to be different skins based on the same MIDP implementation. In general, these emulators implement the MIDP specification faithfully and provide a wide range of functionality.
