Java achieves platform independence by using the concept of the BYTE code. The Java compiler never converts the source code to machine code like that of the C/C++ compiler.
What feature of Java makes it platform independent?
In the case of Java, it is the magic of Bytecode that makes it platform independent. This adds to an important feature in the JAVA language termed as portability. Every system has its own JVM which gets installed automatically when the jdk software is installed.
What feature of Java makes it secure?
The JDK is designed with a strong emphasis on security. At its core, the Java language itself is type-safe and provides automatic garbage collection, enhancing the robustness of application code. A secure class loading and verification mechanism ensures that only legitimate Java code is executed.
Why Java is platform independent and garbage collected programming language?
Java is an object-oriented programming language that includes the following features. Platform Independence – Java applications are compiled into bytecode which is stored in class files and loaded in a JVM. Since applications run in a JVM, they can be run on many different operating systems and devices.
What is the most important feature of Java?
Java has a larger preferences contrasted with different programming languages. Java is simple to write, learn and understand. On the other it is more dynamic than any other available programming language.
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.
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.
Which is the feature of Java?
Java is guaranteed to be write-once, run-anywhere language. On compilation Java program is compiled into bytecode. This bytecode is platform independent and can be run on any machine, plus this bytecode format also provide security. Any machine with Java Runtime Environment can run Java Programs.
Is Java more secure than C++?
Most exploits that involve Java are injection exploits, such as cross-site scripting (XXS), that are not specific to the language itself. In contrast, C has a long and sordid history of exploits going back to the late 1980s (and probably earlier). For these reasons, Java is often considered more secure.
What are the buzzwords in Java?
The Java programming language is a high-level language that can be characterized by all of the following buzzwords:
- Simple.
- Object oriented.
- Distributed.
- Interpreted.
- Robust.
- Secure.
- Architecture neutral.
- Portable.
