Java AWT is an API to developer GUI and window based application in java. Java AWT provide a huge set of reusable GUI component for such as buttons text fill label panel and frame for building GUI at the applications. AWT consist of twelve packages but only two packages are commonly used. . AWT provides a set of classes and interfaces that help the developer to create components such as buttons, text fields, labels, checkboxes, menus, windows. This is a platform-dependent API of Java, that is its implementation depends on the native GUI components of the menus operating system. 1. Features of Java AWT :- The java AWT packages contains the core AWT graphics classes such as text fill. . GUI components classes such as text fill label. . GUI container classes , frame panel. . Layout managers such as flow layout border layout , grid layout. . Custom graphics classes such as col and font. . Platform-dependent :-Uses Native OS components. . Provides GUI Components :- Button, Label, Text F...

Digital logic in design computer organization and architecture microprocessor in the system and interfacing computer networks and operating system. In this you learn the design, development and maintenance of both hardware (physical parts of the computer) and software (programs, applications, operating systems). 1.Scope of Computer Engineering                                                         . Computer Engineering students are taught these things:...

                          Digital Marketing Digital Marketing means promoting products and services using the Internet and digital technology.

                                          Constants   Constants in java refer to fixed values do not change during the execution of a program , Java support several types  of constants as illustrated. .Integer  Constants      An integer constant refer to a sequence of digits , There are three types integers .namely decimal imager octal integers and hexadecimals integers . Decimal integers consist of a set of thing preceded by an optional minus sign Valid of decimals integer constant  .Variables  A variable is an identifier that denotes a storage location seed to store a data value unlike constant that remain unchanged during the execution of a program , a variable may take different values at different times during the execution of the program ,we had used several variable for instance , we used variables length and breath to store the values o...

                                              Java Virtual Machine All language compiler translate source code into machine code for a specific computer .Java compiler also does the same thing ,Then how does java archive architecture neutrality ? The answer  is that the java compiler produces an intermedia code known an bytecode for a machine that does not exits , This   is  a machine is called the java virtual machine and it exits only inside the computer memory , It is a simulated   computer within the computer and does all major machine of a real computer, illustrates the process of compiling a java program into byte code which is also referred to as virtual machine code  The virtual ma chine code is not machine specific code (known as machine code) is  generated by the code interpreter by acting as an intermediary between the vi...
