What are the synchronized methods and synchronized statements in java?
Synchronized Methods are methods that have the keyword synchronized in the method signature. Synchronized statements are pieces of java code that are surrounded by brackets which have the keyword synchronized qualifying them. Both cases mean that - only one thread will be able to access the method or the statement that is synchronized
What is foreign keyword in java?
There is no "foreign" keyword in Java, however, there is a native keyword that declares native methods in a native language, such as C or C++.For full list of keywords in Java see related question.
Is sizeof keyword in Java?
sizeof is not a keyword in Java but many classes have size() or length() methods, which can mean the number of elements, characters, etc. depending on the class.
Inheritance vs instantiation in Java?
Inheritance is simply when you get properties and methods from a superclass, whereas instantiation is actually allocating an object in memory based on your class.
What are the usages of keyword final in java?
It's a built-in keyword that defines an entity that cannot be later modified. It can be used in different aspects within your code (like setting a 'final' class, method (function), or variable).
Is it possible to implement overriding in every inheritance?
Yes. It is possible to implement overriding in every inheritance level. If there are methods of the same name in multiple classes in the hierarchy the one that is closest to the current object gets invoked. The other methods can be specifically invoked using the super keyword.
Difference between super and this in java?

Where does inheritance take place?
Inheritance, in the context of object-oriented programming, takes place between classes where one class (called the sub-class or child class) inherits attributes and methods from another class (called the super-class or parent class). This allows for code reusability and the establishment of a hierarchical relationship between classes.

What is the relationship of policies to strategies?
The relationship between policies and strategies is strong. Policies are the ideas and rules while strategies are methods to execute them.
What is the difference between class inheritance and interface inheritance?
interface inheritance is a misleading term. Interface inheritance would be equivalent to the union of the method signatures of interfaces ( no typo here, an interface may implment multiple other interfaces) Class inheritance - single hierarchy (in C#), and not only the methods are inherited, but also the data members. (interface in C# cannot define data members)
What is foreign keyword in java?

Is sizeof keyword in Java?

What are some research methods and topics ideas for conducting keyword research effectively?
Some research methods for conducting keyword research effectively include using keyword research tools, analyzing competitor keywords, and conducting surveys or interviews. Topics ideas for keyword research could include identifying popular search terms in your industry, understanding user intent behind keywords, and optimizing keywords for voice search.
