sir, pls tell me 1.the differences between platform independent and portability related to java technology 2.how java provides security 3.how can i prove servlet is a single instance multiple thread based serverside technology? all scripting languages are also platform independent!? Java Platform Independence Benefits. Java Programming Java 8 Object Oriented Programming. How is Java platform independent? If we can say, so nearly 80% of the windows executables are also platform independent since you can run them with virtual machines or WINE on Linux etc. JVM is an interpreter. JVM takes bytecode as input and execute it. So java developers aimed at one programming language which can be used irrespective of the platform. Language that Java uses: Java … One of the major features of java includes that why java is called platform independent language. Before understanding this feature we need to know about – Javac – compiler that converts source code to byte code. Because output of java is in bytecode so its not possible to modify by malicious programs thats why java is secure. 1) Describe why Java is platform-independent and portable. Since program in java neither depends on software or hardware of the machine it is running, hence it is called platform independent. What is Java? It is widely used for developing Java applications in laptops, data centers, game consoles, scientific supercomputers, cell phones, etc. sample.java → javac (sample. This bytecode is a platform independent code because it can be executed on several platforms, that is, Write Once and Run Anywhere (WORA) . 3) Describe the six steps of the Linux Boot Process (Startup Sequence) briefly. (Platform represents Operating System). When you compile Java programs using javac compiler it generates bytecode. So how we can say that it is platform independent. How Java is Platform Independent. It is a computing platform for application development. The java compiler converts this java byte code into respective machine code according to the machine it is run on. 2) Describe three general methods for passing parameters to the operating system call. How java is platform independent just because of Bytecode (i.e. Java is fast, secure, and reliable, therefore. Java is developed for emerging need of a programming language for embedded devices. We need to execute this bytecode using JVM (Java Virtual machine) Then, JVM translates the Java bytecode to machine understandable code. Why java is called platform independent language . Output of java is in bytecode so we need to setup JVM on other platform which makes java Platform independent. This java byte code is machine independent,i.e,it does not depends on which machine it is run. They introduced a language finally that is java. portability vs platform independent. Java is a general-purpose, class-based, object-oriented programming language designed for having lesser implementation dependencies. So we can say that the main aim of developing java is platform independence. JVM- interpreter that converts byte code to machine language code. And sure, if Java is platform independent, PHP, ASP, Perl, Python, Ruby etc. Note: Please use this button to report only Software related issues.For queries regarding questions and quizzes, use the comment area below respective pages. Bytecode is the machine understandable code of the JVM (Java Virtual Machine) ) By using Bytecode execution java proves it is a platform independent language. Here, is the process of java bytecode execution.
