Features of Java

Java is a platform independent programming language using which one can write a program that can run under any kind of OS.

It is also architectural neutral because the Java compiler does not generate object code which is machine dependent; rather the source file of a Java program is converted to byte code. To run this byte code we need an interpreter which is called Java Virtual Machine (JVM). Once the JVM is implemented then any Java program can be executed irrespective of the hardware architecture of the computer.

Later on in Java 2, a run time compiler has been added which generates executable code from the byte code on a piece by piece basis. That run time compiler is called Just In Time (JIT).

Technically speaking, Java is a fool proof programming language. Every concept has been well understood before implementation.

Title: Reply for(samarendra swain) why Java does not include multiple inheritance

Java was actually designed to be simple,familiar and object-oriented.To keep it simple and familiar, the language has been made as similar as possible to C++ but without including the unnecessary complexities of the C++ language like multiple inheritance which causes more problems and confusion than it solves.The avoidance of multiple inheritance from Java language is to avoid the "diamond" problem associated with implementation of multiple inheritance.The diamond probem is the ambiguity that arises when two classes B and C inherit from A and another class D is inherited gform both B and C.Now if a method in D calls a method defined in A,which class does it inherit via, B or C?To avoid this situation, multiple inheritance is avoided in Java.Instead we have Java implement multiple inheritance by using interfaces.
