Manish sir is best his teaching and explanation is very clear thanks manish for providing such great stuff for everyone those who want to make their carrier in IT it will be very helpfull for us..
interface in Java is a blueprint for a class that defines a contract of abstract methods that the implementing class must fulfill Features: 1. Abstract Methods: Methods are implicitly public and abstract by default. No method body is provided. 2. Constants: Variables in interfaces are public, static, and final by default. 3. Default and Static Methods (Introduced in Java 8): Default Methods: Can have a method body and allow backward compatibility. Static Methods: Belong to the interface and can be called without an instance. 4. Inheritance: An interface can extend another interface. A class can implement multiple interfaces. 5. No Constructor: Interfaces cannot have constructors or be instantiated directly. 6. Multiple Inheritance: A class can implement multiple interfaces, achieving multiple inheritance.

literally to every automation tester it has become difficult to crack the coding round can you please create more such videos 🙏
Hi sir, how much yoe she had
Ur really providing a good content thanks for all sir
