10+ Tollman International Interview Questions and Answers

Different programming languages exist to cater to different needs and preferences of developers.

• Different languages have different syntax, features, and performance characteristics.

• Some languages are better suited for certain tasks, such as web development or data analysis.

• Languages also evolve over time to adapt to changing technology and user needs.

• Examples of popular programming languages include Java, Python, C++, and JavaScript.

Odd numbers are not divisible by 2 and end with 1, 3, 5, 7, or 9. Even numbers are divisible by 2.

• Odd numbers end with 1, 3, 5, 7, or 9

• Even numbers are divisible by 2

• Examples: 1, 3, 5, 7, 9 are odd. 2, 4, 6, 8, 10 are even.

if is used for a single condition, elif is used for multiple conditions in a chain

• if statement is used to execute a block of code if a condition is true

• elif statement is used to check multiple conditions in a chain and execute a block of code as soon as one of the conditions is true

• if can be used alone or with elif and else statements to create more complex conditional logic

Full stack web development involves working on both the front-end and back-end of a web application.

• Involves working on both front-end (client-side) and back-end (server-side) development

• Requires knowledge of languages and frameworks like HTML, CSS, JavaScript, Python, Django, React, etc.

• Developers are responsible for designing, building, and maintaining the entire web application

• Examples: MEAN stack (MongoDB, Express.js, AngularJS, Node.js), MERN stack (MongoDB, Express.js, ...read more

Programming in real life involves using code to solve practical problems and automate tasks.

• Automating repetitive tasks like data entry or file management

• Developing software applications to streamline business processes

• Creating websites and mobile apps for communication and entertainment

• Analyzing data to make informed decisions

• Implementing algorithms for efficient problem-solving

OOps concepts like inheritance, polymorphism, encapsulation, and abstraction are used in gaming apps to create modular and extensible code.

• Inheritance is used to create different types of game characters with shared attributes and behaviors.

• Polymorphism allows for different actions to be performed based on the type of game object.

• Encapsulation is used to hide implementation details and protect game data from external manipulation.

• Abstraction is used to create modular and reus...read more

Java is an object-oriented programming language because it allows for the creation of objects, which can contain data and methods.

• Java supports the four pillars of object-oriented programming: encapsulation, inheritance, polymorphism, and abstraction.

• Objects in Java can be easily reused and extended through inheritance.

• Java classes and objects help in organizing code and making it easier to maintain and understand.

• Example: In Java, you can create a class 'Car' with properties...read more

Data types are classifications of data items that determine the kind of operations that can be performed on them.

• Data types define the type of data a variable can hold, such as integers, strings, floats, etc.

• Examples of data types in Python include int, str, float, list, tuple, dict, etc.

Programming is the process of designing and building instructions for a computer to execute tasks.

• Programming involves writing code using specific syntax and rules.

• It requires problem-solving skills to create algorithms and logic.

• Programming languages like Python, Java, and C++ are used to communicate with computers.

• Programs can range from simple scripts to complex software applications.

Java is independent platform due to its ability to run on any hardware or operating system.

• Java programs are compiled into bytecode which can be run on any Java Virtual Machine (JVM)

• JVM acts as an abstraction layer between the Java program and the underlying hardware/OS

• Write once, run anywhere principle allows Java programs to be platform-independent
