Where To Get Java Programming Questions Help From Experts

Are you looking for a career option in Java programming and have done a lot of preparation for the interview Are you still worried about the interview questions? Then no worries! We are here to assist you with your Java programming questions. In this article, we will provide you with the top 7 Java programming questions. And also reveal the websites where you can take Java programming questions help.

Taking question help will support you to improve your knowledge about Java programming concepts. But make sure that you must consider the best Java programming questions to help experts. And do not forget to check the qualification and working experience of the experts. So, let's start with the questions. But before that, take a look at some details about the Java programming language.

An overview of Java programming language
Java is a programming language that was developed by James Gosling in 1991. It is used to develop desktop, server, and mobile applications.

Java is an object-oriented programming language. And the OOPs concepts make it very powerful and easy to maintain code. It also has many features that are not present in other languages like static typing, automatic garbage collection, memory management, etc.

Moreover, every programmer must know the basics of Java. This allows users to write code in any other language.

Top 7 Java programming questions asked in Java interview

Q1) What does the start method of Thread do
A) The thread’s start method puts the thread in a ready state. And it makes the thread eligible to run. start method automatically calls the run method.

Q2) Which class is the wait method defined in
A) The wait method is defined in the Object class. This is the ultimate superclass of all others. So the Thread class and any Runnable implementation inherit this method from Object.

The wait method is normally called on an object in a multi-threaded program to allow other threads to run. The method should only be called by a thread. It has ownership of the object’s monitor. This usually means it is in a synchronized method or statement block.

Q3) What are the different types of inner classes
A) Nested top-level classes, Member classes, Local classes, Anonymous classes

Nested top-level classes- In case, you declare a class within a class and specify the static modifier. Then the compiler treats the class just like any other top-level class.

Any class outside the declaring class accesses the nested class with the declaring class name acting similarly to a package. Eg, outer. inner. Top-level inner classes implicitly have access only to static variables. There can also be inner interfaces.

Member classes - Member inner classes are just like other member methods and member variables and access to the member class is restricted, just like methods and variables. This means a public member class acts similarly to a nested top-level class.

The primary difference between member classes and nested top-level classes is that member classes have access to the specific instance of the enclosing class.

Local classes - Local classes are like local variables, specific to a block of code. Their visibility is only within the block of their declaration.

For the class to be useful beyond the declaration block, it would need to implement a more publicly available interface. Because local classes are not members, the modifiers public, protected, private, and static are not usable.

Anonymous classes - Anonymous inner classes extend local inner classes one level further. As anonymous classes have no name, you cannot provide a constructor.

Q4) Where does the support for threading lie
A) The thread support lies in Java. lang.Thread, Java. lang.Object and JVM.

Q5) In which class would you find the methods notify,notifyAll, and wait
A) Object class

Q6) What is threaded programming and when is it used
A) Threaded programming is normally used when a program is required to do more than one task simultaneously. Threading is often used in applications with graphical user interfaces. A new thread may be created to do some processor-intensive work. On the other hand, the main thread keeps the interface responsive to human interaction.

The Java programming language has threaded programming facilities built-in. That is why it is relatively easy to create threaded programs. However, multi-threaded programs introduce a degree of complexity that is not justified for most simple command-line applications.

Q7) Why not override Thread to make a Runnable
A) There is little difference in the work required to override the Thread class compared with implementing the Runnable interface. These both require the body of the run method.

However, it is much simpler to make an existing class hierarchy runnable. Because any class can be adapted to implement the run method. A subclass of Thread cannot extend any other type. Therefore, application-specific code would have to be added to it rather than inherited.

Separating the Thread class from the Runnable implementation also avoids potential synchronization problems between the thread and the run method. A separate Runnable generally gives greater flexibility in the way. It allows runnable code to be referenced and executed.
