![]() It is a set of statements in a High-Level programming language. Five commonly used Java reserved words are: Reserved words are also known as keywords. Due to this, reserved words can’t be used as names for variables, methods, classes or any other identifier. In Java, a reserved word is a word that has a predefined meaning in the language. What are Java reserved words? Name any five. Three packages of Java Class Library are: Name three packages of Java Class Library. JVM is platform specific, each platform has its own JVM. Java Virtual Machine (JVM) is a software that takes Bytecode as input, converts it into Machine code of the specific platform it is running on and executes it. It needs to be converted into Machine Code first. Bytecode can't be executed directly on the processor. ![]() Java compiler converts Java source code into an intermediate binary code called Bytecode. As it reads the program line by line so the errors are reported one by one. The compiler processes the complete source program at once and if there are compilation errors, they are all reported together at once.Īn interpreter is a program that reads a source program line by line, converts each line into its equivalent machine code and executes it. It uses a compiler as well as an interpreter.Ī compiler is a program that translates a source program written in some high-level programming language into a target program in another low-level programming language without changing the meaning of the program. It provides us Write Once, Run Anywhere (WORA) feature. It is an Object Oriented Programming Language. Oak was renamed to Java and on 23rd of May 1995, Sun microsystems made its first public release. By 1994 the team refocussed their efforts towards internet programming with Oak as it didn't find much traction in consumer electronics space. Over the next 18 months, in 1992 the team created a new programming language which they called “Oak”. In 1991, at Sun Microsystems, Green team led by James Gosling started working on a new technology for consumer electronic devices. ![]() Give a brief historical development of Java. ![]() James Gosling developed Java programming language. Who developed Java? What was it initially called? ![]()
