What is the main features of Java?

Features of Java Programming Language

  • Simple and Familiar. Java is simple because:
  • Compiled and Interpreted. Usually, a computer language can be either compiled or interpreted.
  • Platform Independent.
  • Portable.
  • Architectural Neutral.
  • Object-Oriented.
  • Robust.
  • Secure.

What are the 4 features of Java?

Following are the notable features of Java:

  • Object Oriented. In Java, everything is an Object.
  • Platform Independent.
  • Simple.
  • Secure.
  • Architecture-neutral.
  • Portable.
  • Robust.
  • Multithreaded.

What is encapsulation in Java?

Encapsulation in Java is a mechanism of wrapping the data (variables) and code acting on the data (methods) together as a single unit. In encapsulation, the variables of a class will be hidden from other classes, and can be accessed only through the methods of their current class.

What is dynamic in Java?

When the compiler resolves the method call binding during the execution of the program, such a process is known as Dynamic or Late Binding in Java. We also call Dynamic binding as Late Binding because binding takes place during the actual execution of the program.

What are the Java 7 features?

The important features of JavaSE 7 are try with resource, catching multiple exceptions etc.

  • String in switch statement (Java 7)
  • Binary Literals (Java 7)
  • The try-with-resources (Java 7)
  • Caching Multiple Exceptions by single catch (Java 7)
  • Underscores in Numeric Literals (Java 7)

How many features are there in Java?

Understand 9 features of Java programming language.

Which is not Java features?

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. Due to pointers, most of the users consider C-language very confusing and complex.

What are the advantages of 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.

What are the benefits of encapsulation in Java?

Advantage of Encapsulation in Java

  • The encapsulated code is more flexible and easy to change with new requirements.
  • It prevents the other classes to access the private fields.
  • Encapsulation allows modifying implemented code without breaking other code that has implemented the code.

What is encapsulation in Java example?

Encapsulation in Java is a process of wrapping code and data together into a single unit, for example, a capsule which is mixed of several medicines. We can create a fully encapsulated class in Java by making all the data members of the class private. The Java Bean class is the example of a fully encapsulated class.

Is Java dynamic or static?

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.

What is static and dynamic in Java?

In Java static binding refers to the execution of a program where type of object is determined/known at compile time i.e when compiler executes the code it know the type of object or class to which object belongs. While in case of dynamic binding the type of object is determined at runtime.

What are some of the features of Java?

Java is robust as it is capable of handling run-time errors, supports automatic garbage collection and exception handling, and avoids explicit pointer concept. Java has a strong memory management system. It helps in eliminating errors as it checks the code during both compile and runtime.

Why is Java known as a platform independent language?

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 is Java an architecture neutral programming language?

Java is architecture neutral because there are no implementation dependent features, for example, the size of primitive types is fixed. In C programming, int data type occupies 2 bytes of memory for 32-bit architecture and 4 bytes of memory for 64-bit architecture. However, it occupies 4 bytes of memory for both 32 and 64-bit architectures in Java.

Which is the best way to describe Java?

1 Simple: Java is a simple language because its syntax is simple, clean, and easy to understand. 2 Object-Oriented: In Java, everything is in the form of the object. 3 Robust: Java makes an effort to check error at run time and compile time.
