Yes, Java is an object-oriented programming language.

• Java supports all the features of OOP such as encapsulation, inheritance, and polymorphism.

• Objects are created from classes in Java.

• Example: class Car { String make; int year; } Car myCar = new Car();

• Java also has interfaces which allow for abstraction and multiple inheritance.

Lists are dynamic and can hold different data types, while arrays are fixed in size and can only hold one data type.

• Lists can be resized during runtime, while arrays cannot.

• Lists are implemented as classes in most programming languages, while arrays are primitive data types.

• Lists can hold different data types, while arrays can only hold one data type.

• Lists are more flexible and easier to work with, while arrays are faster and more efficient for certain operations.

OOPs concepts are the fundamental principles of object-oriented programming.

• Encapsulation: bundling of data and methods that operate on that data

• Inheritance: ability of a class to inherit properties and characteristics from its parent class

• Polymorphism: ability of objects to take on multiple forms or behaviors

• Abstraction: hiding of complex implementation details and showing only the necessary information

Mine planning involves several steps to ensure efficient and safe extraction of minerals.

• Conduct geological surveys to identify mineral deposits

• Design mine layout and infrastructure

• Develop mining methods and schedules

• Estimate costs and create budget

• Implement safety measures and environmental regulations

• Monitor production and adjust plans as needed

A program on a calculator involves entering mathematical operations to obtain a result.

• Use the appropriate mathematical symbols (+, -, *, /) to perform calculations.

• Ensure the correct order of operations is followed (PEMDAS).

• Check for errors in input and output to ensure accuracy.

• Examples: 2 + 3 = 5, 10 * 5 = 50, 15 / 3 = 5
