Why Should Learn Online Java Course in Noida?

Every programming language other than Java has its own set of rules to declare, define, and work on its components. Reading and learning about all of them together is an arduous task. Therefore here you will be learning basic Syntax, keywords, and operators, which will be required to create a program at the beginning of java language. Also, you will be learning OOPS concepts in the Best IT & Professional Training Institute.

OOPs, that is a programming concept that works on the principle that objects are the most crucial part of the program. It lets users create the objects that they want and, after that, develop methods to handle those objects. Manipulating these objects to get results is the goal of Object-Oriented Programming language.

Frequently Asked JAVA Course Interview Questions:

1: Why Java is a platform-independent language?

Ans: Java language was developed in such a way that it does not depend on any hardware or software because the compiler compiles the code and then converts it to platform-independent byte code which can be run on multiple systems. The only condition to run that byte code is for the machine to have a runtime environment (JRE) installed in it.

2: What gives Java its 'write once and run anywhere nature?

The bytecode. Java compiler converts the Java programs into the class file (Byte Code) which is the intermediate language between source code and machine code. This bytecode is not platform specific and can be executed on any computer.

3: Why Java is not 100% Object-oriented?

Ans: Java is not 100% Object-oriented because it makes use of eight primitive data types such as boolean, byte, char, int, float, double, long, and short which are not objects.

4: What is the JIT compiler in Java?

Ans: JIT stands for Just-In-Time compiler in Java. It is a program that helps in converting the Java bytecode into instructions that are sent directly to the processor. The JIT compiler is enabled in Java and is activated whenever a Java method is invoked. The JIT compiler then compiles the bytecode of the invoked method into native machine code, compiling it “just in time” to execute.

5: What is Java String Pool?

Ans: Java String pool refers to a collection of Strings which are stored in heap memory. In, whenever a new object is created, the String pool first checks whether the object is already present in the pool or not.

6: What is constructor chaining in Java?

Ans: In Java, constructor chaining is the process of calling one constructor from another concerning the current object. Constructor chaining is possible only through legacy where a subclass constructor is responsible for invoking the superclass’ constructor first. There could be any number of classes in the constructor chain.

7: What are the prominent features of Java?

Ans: The features of Java are:

  • Dynamic: Java is more dynamic when compared to C++ and C. Java is designed in such a way that it is adaptable to any evolving environment.
  • Simple: Java is very easy to learn and code.
  • Object-oriented: In Java, everything is based on objects.
  • Secure: Java provides a secure platform to develop safe and virus-free applications.
  • Platform Independent: Unlike C and C++, when we compile Java code it is compiled into platform-independent bytecode rather than platform-specific machine code.

8: Define Object in Java?

Ans: The instance of a class is called an object. Every object in Java has both state and behavior. The state of the object is stored in fields and the behavior of the objects is defined by methods.

9: Define JVM?

Ans: JVM is the abbreviation for Java Virtual Machine. It is a virtual machine that provides a runtime environment to write code. JVM is a part of JRE (Java Runtime Environment) and is used to convert the bytecode into machine-level language. This machine is responsible for allocating memory.

10: What is the significant difference between JVM, JRE, and JDK?

Ans: We can understand the difference between JVM, JDK, and JRE by the following diagram:

  • JVM: Java Virtual Machine is the main part of Java programming, which provides platform independence. JRE and JDK both contain JVM to run our Java programs.
  • JDK: This development kit is mainly used for developing programs.
  • JRE: Java Runtime Environment is mainly used for running Java programs.
