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 java applications are 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. This byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever platform it is being run on.
What is meant by java is architecture neutral?
architecture neutral -> it means the java program can be run on any processor irrespective of its vendor and architecture. so it avoids rebuilding problem.
Why is java considered as architectural neutral and secure?
10) Secure: Java was designed with security in mind. … Java programs are compiled into byte-code format which does not depend on any machine architecture but can be easily translated into a specific machine by a Java Virtual Machine (JVM) for that machine.
Why Java is a dynamic language?
Java is considered to be more dynamic than C or C++ since it is designed to adapt to an evolving environment. Java programs can carry an extensive amount of run-time information that can be used to verify and resolve accesses to objects at run-time.
Why Java is not object oriented?
Java is not fully object oriented because it supports primitive data type like it,byte,long etc.,which are not objects. Because in JAVA we use data types like int, float, double etc which are not object oriented, and of course is what opposite of OOP is. That is why JAVA is not 100% objected oriented.
How Java is different from C and C++?
Java is a true object-oriented language while C++ is basically C with object-oriented extension.
Java and C++
|C++ Programming||Java Programming|
|It supports multiple inheritances of classes.||It does not support multiple inheritances of classes. This is accomplished using a new feature called “Interface”.|
How Java is robust and architecture neutral?
Java compiler generates an architecture-neutral object file format, which makes the compiled code executable on many processors, with the presence of Java runtime system.
Who invented Java?
Java was created at Sun Microsystems, Inc., where James Gosling led a team of researchers in an effort to create a new language that would allow consumer electronic devices to communicate with each other. Work on the language began in 1991, and before long the team’s focus changed to a new niche, the World Wide Web.
Is Java static or dynamic?
Java is statically-typed, so it expects its variables to be declared before they can be assigned values. Groovy is dynamically-typed and determines its variables’ data types based on their values, so this line is not required.
Why Java is known as robust and dynamic?
Java is robust because it utilizes strong memory management. There is an absence of pointers that bypasses security dilemmas. 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.
How Java is secured?
Java is secure due to the following reasons: Java programs run inside a virtual machine which is known as a sandbox. Java does not support explicit pointer. Byte-code verifier checks the code fragments for illegal code that can violate access right to object.
