Java uses call by value.

• Java passes a copy of the value of a variable to a method, not the actual variable itself.

• Changes made to the parameter inside the method have no effect on the original variable.

• However, if the parameter is an object reference, the reference is passed by value, so changes to the object itself will be reflected outside the method.

Java is platform-independent due to its bytecode and virtual machine architecture.

• Java code is compiled into bytecode, which can run on any platform with a Java Virtual Machine (JVM).

• JVM acts as an interpreter, translating bytecode into machine code specific to the platform it is running on.

• Encapsulation, inheritance, and polymorphism are key principles of OOP.

• Examples of OOP languages include Java, C++, and Python.

Oops concepts in Java refer to Object-Oriented Programming principles like Inheritance, Polymorphism, Encapsulation, and Abstraction.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Polymorphism: Ability of an object to take on many forms.

• Encapsulation: Bundling of data with the methods that operate on that data.

• Abstraction: Hiding the implementation details and showing only the necessary features of an object.

C Python is a C extension module that allows C code to call Python functions and manipulate Python objects.

• Cython is a popular tool for writing C extensions for Python

• NumPy is a Python library that provides support for large, multi-dimensional arrays and matrices

• Pygame is a set of Python modules designed for writing video games

• Scikit-learn is a Python library for machine learning built on top of NumPy and SciPy

Building blocks of Java include variables, data types, operators, control structures, and classes.

• Variables are used to store data

• Data types define the type of data that can be stored in a variable

• Operators are used to perform operations on data

• Control structures are used to control the flow of a program

• Classes are used to define objects and their behavior

Questions from education

• Can you provide an example of a time when you had to adapt your communication style to effectively convey information to someone with a different educational background?

• How do you stay up to date with industry developments and incorporate them into your work?

• Can you describe a successful training program you have implemented in the past?

OOPS concepts refer to Object-Oriented Programming concepts which include inheritance, encapsulation, polymorphism, and abstraction.

• Inheritance: Allows a class to inherit properties and behavior from another class. Example: Parent class 'Animal' and child class 'Dog'.

• Encapsulation: Bundling data and methods that operate on the data into a single unit. Example: Class 'Car' with private variables and public methods.

• Polymorphism: Ability to present the same interface for differe...read more
