History of Java. In 1991, Sun Microsystems has a project to develop a program which is designed for interactive televisions such as cable boxes. Then they started a team called Green and wanted to develop in such a way it could run on any hardware devices, should be hardware independent. Under the supervision on James Gosling the green team able to develop and named as OAK. Since the name OAK was already existed in programming language, they finally named it as JAVA. Since there is a huge popularity

CISS3315 Mr. Gray Use of Java in Browsers Sun developed plugins for Java back in the 1990’s as a way to bring app-like features to web browsers. At the time, this seemed like a nice feature to have and it changed the look of web browsers forever. However, there are vulnerabilities with the technology that have never been fixed, even once taken over by Oracle. These issues affect the security of the plugins and have contributed to its decline and lack of support. While Java is still favored by developers

Linguistic composition of Java? 2. Specifications of the Java programming language? 3. The goals of Java? Programming Language is artificial language aims to conveys the instructions to the device and especially computer device. Also we can be used to setting up programs to control the behavior of the device or to express to algorithm. Programming Language divided to high-level language it means that it is close to the language that it understood by humans such as: C and Java. On other hand there

RATIONAL NUMBER CLASS IN JAVA AIM To write a program to find the rational form of rational number. ALGORITHM 1. Start the program. 2. Declare the class name as rational and assign num, den as two parameters. 3. Declare constructor as rational and numerator and denominator as parameter. 4. Then write to string () method to print the rational class object as a string. 5. To get the GCD value using static method use GCD (int m, int n) method. 6. Get the num and den from the

Pre- Defined Exceptions So as to manage synchronous and asynchronous special cases, JAVA consists of java.lang.Error class. Synchronous are of two types: • Checked exceptions which are covered during Compilation of the program • Unchecked exceptions are found during Run time of the program like NoClassFoundException etc Try-Catch-Finally Try block in JAVA code encloses the thrown exceptions while Catch block is to catch them. While Finally contains the codes to execute commands like closing resultsets

CHAPTER-1 INTRODUCTION The Java Ring is a stainless-steel ring, 16-millimeters (0.6 inches) in diameter that houses a 1-million-transistor processor, called an iButton. The ring has 134 KB of RAM, 32 KB of ROM, a real-time clock and a Java virtual machine, which is a piece of software that recognizes the Java language and translates it for the user's computer system. At Celebration School, the rings have been programmed to store electronic cash to pay for lunches, automatically unlock
