Features of java programming language

Compiled and interpreted Platform – IndependentObject – OrientedRobust and SecureDistributedMultithreaded Dynamic and Extensible Compiled and interpreted:-                Usually a computer language is either compiled or interpreted. Java combines both these approaches thus making Java a two stage system. First, Java compiler translates sources code into what is known as byte code instruction. Byte codes are not machine instructions and therefore, in the second stage. Java...

Structure of JAVA program

 A JAVA program may contains many classes of which only one class defines a main method. Classes contain data members and methods that operated on the data members of the class. Methods may contain data type declaration and executed statements. To write a Java program, we first define classes and then put them together. A Java program may contain one or more sections...
