The platform independent byte code can be carried to any platform for execution that makes java code portable. Introduction to java 1. Java is a programming language created by James Gosling from Sun Microsystems (Sun) in 1991. Before we start learning Java, lets get familiar with common java terms. 4 main concepts of Object Oriented programming are: Java is considered as one of simple language because it does not have complex features like Operator overloading, Multiple inheritance, pointers and Explicit memory allocation. As discussed above, javac compiler of JDK compiles the java source code into bytecode so that it can be executed by JVM. It was developed by James Gosling and Patrick Naughton. Next the notes explain how to create a Java program with the Windows Notepad editor and how to run it using the Java Development Kit. 3) In third phase, JVM executes the bytecode generated by compiler. Instructor—Russel Gauthier, 2009 The bytecode is saved in a .class file by compiler.

Before, we discuss about JVM lets see the phases of program execution. By contrast, Java® programs are compiled into machine-independent byte code. This is not meant to be a comprehensive Java reference. Each operating system has different JVM, however the output they produce after execution of bytecode is same across all operating systems. As the name suggests this is complete java development kit that includes JRE (Java Runtime Environment), compilers and various tools like JavaDoc, Java debugger etc. Compiler(javac) converts source code (.java file) to the byte code(.class file). Dynamic binding is slower than static binding because it occurs in run time and finds some time to find out actual method to be called, Your email address will not be published. Introduction . No notes for slide. standard Java API for database-independent connectivity between the Java programming language and a wide range of databases Object: It is a basic unit of Object-Oriented Programming and represents the real-life entities.

Java supports multithreading. Java is a popular programming language, created in 1995. We em-phasize the concepts of a data type (a set of values and a set of operations on them) and an object (an entity that holds a data-type value) and their implementation using Java… Hence, the identifier exampleNameInJava is differ-ent from ExampleNameInJava. Java Development Kit 8 Update Release Notes Release Notes for all JDK Release Versions . So, now that we understood that the primary function of JVM is to execute the bytecode produced by compiler. bytecode Each operating system has different JVM, however the output they produce after execution of bytecode is same across all operating systems. Robust means reliable. ), It is one of the most popular programming language in the world, It has a huge community support (tens of millions of developers), Java is an object oriented language which gives a clear structure to programs and allows code to be reused, lowering development costs. As mentioned above, JVM executes the bytecode produced by compiler. We don’t have pointers and we cannot access out of bound arrays (you get ArrayIndexOutOfBoundsException if you try to do so) in java. Unless otherwise indicated, Reading refers to the course text: Data Structures and Problem Solving Using Java (3/E), Addison Wesley, ISBN: 0-321-32213-4, 2006.See also Weiss's … That’s why several security flaws like stack corruption or buffer overflow is impossible to exploit in Java.
