This document discusses Java data types. It explains that variables reserve memory locations and the data type determines what memory is allocated and what values can be stored. There are two main data types in Java: primitive types and reference types. The primitive types are predefined by Java and include byte, short, int, long, float, double, boolean and char. Reference types refer to objects.

Both examples demonstrate using structures to organize related data in C programming.
A&D - UML
A&D - UMLvinay arora UML (Unified Modeling Language) is a standardized modeling language used to visualize, specify, construct, and document software systems. It uses mainly graphical notations to express object-oriented analysis and design, simplifying the complex process of software design. Some key reasons to use UML include that it uses clear graphical notation rather than natural language, helps acquire an overall view of a system, and is not dependent on any one programming language. Common UML diagrams include use case diagrams, class diagrams, sequence diagrams, collaboration diagrams, and state diagrams. UML modeling tools allow creating and managing UML diagrams and have become an important part of modern software design.

Political History of Pala dynasty Pala Rulers NEP.pptxArya Mahila P. G. College, Banaras Hindu University, Varanasi, India. The Pala kings were people-protectors. In fact, Gopal was elected to the throne only to end Matsya Nyaya. Bhagalpur Abhiledh states that Dharmapala imposed only fair taxes on the people. Rampala abolished the unjust taxes imposed by Bhima. The Pala rulers were lovers of learning. Vikramshila University was established by Dharmapala. He opened 50 other learning centers. A famous Buddhist scholar named Haribhadra was to be present in his court. Devpala appointed another Buddhist scholar named Veerdeva as the vice president of Nalanda Vihar. Among other scholars of this period, Sandhyakar Nandi, Chakrapani Dutta and Vajradatta are especially famous. Sandhyakar Nandi wrote the famous poem of this period 'Ramcharit'.

- 1. Java – Data Type Organized By: Vinay Arora Assistant Professor CSED, Thapar University www.slideshare.net/aroravinay
- 2. Vinay Arora CSED Data type/s for the variable/s Variables are nothing but reserved memory locations to store values. This means that when you create a variable you reserve some space in memory. Based on the data type of a variable, the operating system allocates memory and decides what can be stored in the reserved memory. There are two data types available in Java: Primitive Data Types Reference/Object Data Types
- 3. Vinay Arora CSED Primitive Data Types There are eight primitive data types supported by Java. Primitive data types are predefined by the language and named by a keyword. Byte Short Int Long Float Double Boolean Char
