It allows creating objects of the class dynamically, invoking their methods and also supplying data to the method arguments if present. Simple beginner friendly graphical user interface. It was created for teaching Object Oriented programming to computer science students.
As low-level programming languages are platform specific hence a compiler is specific to a language.īlueJ is an integrated development environment for Java. Give your comments.Ī compiler translates a source program written in some high-level programming language into a target program in another low-level programming language. IDE isn't essential for developing Java programs but it makes the process easier and efficient.ĩ. JDK is essential for developing Java programs.

JDK includes tools like Compiler, Interpreter, Java libraries, etc.īlueJ provides tools like Code Editor, Debugger, Syntax Highlighting, etc. JDK or Java Development Kit is the set of tools required to compile and run Java programsīlueJ is an IDE or Integrated Development Environment for developing Java programs. 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:ħ. Name three packages of Java Class Library. JVM is platform specific, each platform has its own JVM.Ħ.

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 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? The words which are preserved with the system are called keywords/reserved words that can not be used as variable names in Java programming.Ī single line comment is represented by the symbol // in Java programming.īlueJ is a window based platform to operate Java programs. In Java, the package used to find power raised to any base is java.lang. Fill in the blanks with appropriate words
