Often asked: Why Is Java Platform Independent?

Why Java is platform independent and JVM is platform dependent?

Due to this byte code java is platform independent. JVM is platform dependent because it takes java byte code and generates byte code for the current operating system. So Java software is platform dependent but Java language is platform independent because different operating system have different JVMs.

Why Java is platform neutral or independent language?

How is the Java platform independent? Java is Platform Neutral because the same Java code will run on multiple platforms (Operating Systems) without modification, provided that the code does not intentionally put any specific demands on the system, holding true to the slogan, “Write Once, Run Anywhere”.

Why is Java platform independent and portable?

The idea is that the Java language is portable (or, more precisely, the compiled byte code is portable). The Java code is compiled by the compiler and converted into bytecode. This bytecode is a platform independent code because it can be executed on several platforms, that is, Write Once and Run Anywhere (WORA).

Why Java is secure and platform independent?

Java is platform independent because it is different from other languages like C, C++, etc. which are compiled into platform specific machines while Java is a write once, run anywhere language. A platform is the hardware or software environment in which a program runs.

Why Java is called Robust?

Java is robust because it utilizes strong memory management. There is automatic garbage collection in Java which runs on the Java Virtual Machine to eliminate objects which are not being accepted by a Java application anymore. There are type-checking mechanisms and exception-handling in Java.

What is difference between JDK JRE and JVM?

JDK is a software development kit whereas JRE is a software bundle that allows Java program to run, whereas JVM is an environment for executing bytecode. The full form of JDK is Java Development Kit, while the full form of JRE is Java Runtime Environment, while the full form of JVM is Java Virtual Machine.

Who is the father of Java language?

James Arthur Gosling, often referred to as “Dr. Java”, OC (born May 19, 1955) is a Canadian computer scientist, best known as the founder and lead designer behind the Java programming language.

Is java operating system independent?

Java is OS independent language because SAME source code will work in any OS. The issue you’re facing is about the Virtual Machine, which translates java bytecode to each OS, so, Chrome OS still does not support Java because JVM for Chrome has not been developed (yet).

Why is C++ not platform independent?

In case of C or C++ (language that are not platform independent), the compiler generates an.exe file which is OS dependent. When we try to run this.exe file on another OS it does not run, since it is OS dependent and hence is not compatible with the other OS.

In which language Java is written?

The very first Java compiler was developed by Sun Microsystems and was written in C using some libraries from C++. Today, the Java compiler is written in Java, while the JRE is written in C.

Which is not a Java feature?

Hence, the correct answer is option (a). 2) Which of the following is not a Java features? Explanation: The Java language does not support pointers; some of the major reasons are listed below: One of the major factors of not using pointers in Java is security concerns.

How we can say Java is portable?

Java is known as a ” portable language” because Java code can execute on all major platforms. What’s more, once you’ve compiled your Java source to “byte-code”.

Why pointers are not used in Java?

So overall Java doesn’t have pointers (in the C/C++ sense) because it doesn’t need them for general purpose OOP programming. Furthermore, adding pointers to Java would undermine security and robustness and make the language more complex.

What are the advantages of using Java?

The advantages of Java are as follows:

  • Java is easy to learn. Java was designed to be easy to use and is therefore easy to write, compile, debug, and learn than other programming languages.
  • Java is object-oriented. This allows you to create modular programs and reusable code.
  • Java is platform-independent.

Is Java less secure?

Java is often cited as the most secure programming language. As with other aspects of cybersecurity, the level of programming language security depends on what we mean by “secure.” It’s true that Java has fewer identified vulnerabilities than some other commonly used languages.
