architecture neutral -> it means
the java program can be run on any processor irrespective of its vendor and architecture
. so it avoids rebuilding problem.
What is mean by architecture neutral in Java?
The format of this system-
independent binary code
is architecture neutral. If the Java run-time platform is made available for a given hardware and software environment, an application written in Java can then execute in that environment without the need to perform any special porting work for that application.
What is meant by architecture neutrality?
Software that is designed without regard to the target platform
. Software is often written to maximize the performance of a specific hardware platform, but such software must be modified to make it run on other hardware.
Why is Java is considered an architecture neutral language?
Why is java is considered an architecture – neutral language?
It can run on many different CPUs with only one compilation
. … Android Studio using Java.
Why is Java architectural neutral and platform independent?
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” .
Is C architecture neutral?
Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform-independent byte code.
Is JVM architectural neutral?
Architecture Neutral:
Java is an Architecture neutral programming language
because, java allows its application to compile on one hardware architecture and to execute on another hardware architecture.
Why bytecode is called bytecode?
The name bytecode stems
from instruction sets that have one-byte opcodes followed by optional parameters
. … Bytecode may often be either directly executed on a virtual machine (a p-code machine i.e., interpreter), or it may be further compiled into machine code for better performance.
What are the advantages of Java?

What is identifier in Java?
Identifiers in Java are
symbolic names used for identification
. They can be a class name, variable name, method name, package name, constant name, and more. … For every identifier there are some conventions that should be used before declaring them.
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 is the most important feature of Java?
Platform Independent
The most significant feature of Java is that it provides platform independence which leads to a facility of portability, which ultimately becomes its biggest strength. Being platform-independent means a program compiled on one machine can be executed on any machine in the world without any change.
Is Python architecture neutral?
It’s also
architecture-neutral and high performance
. These features make Java a very popular language choice for enterprise technology. In contrast, Python was designed to be a multi-purpose language that strives to be readable, explicit, and simple.
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 Java is secured?
Because Java compiles as bytecode which then runs inside a Virtual machine, it cannot access the computer it runs on like a natively compiled program can. The general reason why Java is considered to be more secure than, say C, is
because it handles memory management for you
.
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
.
