Java feature includes platform independence, object-oriented programming, and automatic memory management.

• Platform independence allows Java programs to run on any platform without recompilation.

• Object-oriented programming supports concepts like inheritance, encapsulation, and polymorphism.

• Automatic memory management through garbage collection helps in managing memory efficiently.

Encapsulation in Java is the concept of wrapping data (variables) and code (methods) together into a single unit, known as a class.

• Encapsulation helps in data hiding, as the internal state of the object is hidden from the outside world.

• It allows for better control over the data by providing getter and setter methods to access and modify the data.

• Encapsulation also helps in maintaining the integrity of the data by preve...read more

Abstract class can have both abstract and non-abstract methods, while interface can only have abstract methods.

• Abstract class can have constructors, member variables, and methods, while interface cannot.

• A class can implement multiple interfaces but can only extend one abstract class.

Abstract classes can have both implemented and abstract methods, while interfaces can only have abstract methods. Abstract classes support single inheritance, interfaces support multiple inheritance.

• Abstract classes can have both implemented and abstract methods, providing more flexibility in design.

• Interfaces can only have abstract methods, promoting a more strict contract for implementing classes.

• Abstract classes sup...read more

Java program to check if a number is prime

• Create a function that takes an integer as input

• Check if the number is less than 2, return false

• Iterate from 2 to the square root of the number, check for divisibility

• If the number is divisible by any number, return false

• Otherwise, return true

A prime number is a number greater than 1 that can only be divided by 1 and itself.

• Prime numbers are integers greater than 1

• They have only two factors: 1 and the number itself

• Examples of prime numbers: 2, 3, 5, 7, 11, 13
