Top Core Java Interview Questions || Core Java Interview Questions and Answers [MOST ASKED]

In Top Core Java Interview Questions and Answers video you will get top 10 tricky core interview question asked in an interview. Also this video is for both Freshers and Experienced canditates.
Udemy Course of Code Decode on Microservice k8s AWS CICD link:
openinapp.co/udemycourse
Course Description Video :
yt.openinapp.co/dmjvd
This video covers Top Java interview Questions And Answers asked in MNCs from both Freshers and Laterals,
Which May include some Questions of java interview questions and Answers like :
Q) Why Java is not 100% Object-oriented?
Because of Primitive data types namely:
boolean, byte, char, int, float, double, long, short
we have wrapper classes which actually “wrap” the primitive data type into an object of that class.
Q) Why pointers are not used in Java? Mostly asked in java interview questions and Answers in MNC to check you basic knowledge of java and programming languages and logics behind them.
Because :
1) They are unsafe.
2) Increases the complexity of the program and since Java is known for its simplicity of code, adding the concept of pointers will be contradicting.
3) Since JVM is responsible for implicit memory allocation, thus in order to avoid direct access to memory by the user, pointers are discouraged in Java
Q) What is JIT compiler in Java?
Q) Why String is immutable in java?
1) String pool requires string to be immutable otherwise shared reference can be changed from anywhere.
2) security because string is shared on different area like file system, networking connection, database connection , having immutable string allows you to be secure and safe because no one can change reference of string once it gets created.
Q) What is a marker interface?
A Marker interface can be defined as the interface having no data member and member functions. In simpler terms, an empty interface is called the Marker interface.
Q) Can you override a private or static method in Java?
As I have told you in previous videos : method overriding is a good topic to ask trick questions in Java.
1) you can not override a private or static method in Java.
2) you cannot override a private method in sub class because it's not accessible there, what you do is create another private method with the same name in the child class.
3) For static methods if you create a similar method with same return type and same method arguments in child class then it will hide the superclass method, this is known as method hiding.
Q) Does “finally” always execute in Java?
Not in following cases
“System.exit()” function
system crash
Q) What Methods Does the Object Class Have?
Java.lang.Object class, parent of all has following methods :
protected Object clone() throws CloneNotSupportedException
Creates and returns a copy of this object.
public boolean equals(Object obj)
Indicates whether some other object is “equal to” this one.
protected void finalize() throws Throwable
Called by the garbage collector on an object when garbagecollection determines that there are no more references to the object.
public final Class getClass() : Returns the runtime class of an object.
public int hashCode(): Returns a hash code value for the object.
Q) How Can You Make a Class Immutable?
Q) What is singleton class in Java and how can we make a class singleton?
This is always been a part of core java interview question :
Equals and Hash code Contract
Its working and many such interview questions and answers will be covered in this video,
we will create more such videos on java interview questions and Answers on our channel.

[@consistentlearners]

Thanks for making such videos. These videos are very helpful for interview preparation. I would like to correct you on one question mentioned in the above video related to JIT compiler. The probable accurate answer to it would be below answer. When a Java program is executed, the JVM interprets the bytecode one instruction at a time. This process is relatively slow, because each bytecode instruction must be interpreted by the JVM. However, when the JVM encounters a loop or frequently executed code, the JIT compiler compiles that bytecode to native machine code and caches the result, so that subsequent executions of the same code can be executed more quickly.

Hi. Method hiding - "If a subclass (child class) defines a static method with the same signature as a static method in the superclass (parent class), the subclass method conceals the one in the superclass". Method hiding occurs because static methods are resolved at compile time. Please, replace "same return type" with "same signature".
