answer:1. What is a lambda expression? Answer: A lambda expression is a concise way to represent an anonymous function that can be passed around as a parameter or stored in a variable. 2. Why are lambda expressions useful in Java? Answer: Lambda expressions simplify the code by reducing the boilerplate code required for anonymous classes. They promote functional programming and make it easier to write code that works with collections or streams of data. 3. How do you define a lambda expression in Java? Answer: A lambda expression consists of a list of parameters, an arrow (->), and a body. For example: (parameter) -> expression. 4. Can a lambda expression access variables from its enclosing scope? Answer: Yes, a lambda expression can access final or effectively final variables from its enclosing scope. 5. What is the difference between functional interfaces and lambda expressions? Answer: Functional interfaces are interfaces that have only one abstract method. Lambda expressions can be used to provide implementations for the abstract methods defined by functional interfaces. 6. What is the purpose of the arrow (->) in a lambda expression? Answer: The arrow (->) separates the list of parameters from the body of the lambda expression. 7. How do you invoke a lambda expression? Answer: You invoke a lambda expression by treating it as an instance of a functional interface. You can call the abstract method defined by the functional interface using the lambda expression. 8. What is the type of a lambda expression? Answer: The type of a lambda expression is determined by the context in which it is used. It must be compatible with the functional interface to which it is assigned. 9. Can a lambda expression throw an exception? Answer: Yes, a lambda expression can throw exceptions. However, the functional interface must declare the exception in its abstract method signature. 10. What is the return type of a lambda expression? Answer: The return type of a lambda expression is inferred from the context in which it is used. If the lambda expression contains a single expression, the return type is the type of that expression. 11. What is a method reference in Java? Answer: A method reference is a shorthand syntax for creating a lambda expression that calls a specific method. 12. How do you write a method reference? Answer: Method references are written using the :: operator, followed by the name of the method or constructor reference. For example: ClassName::methodName or ClassName::new. 13. Can a lambda expression access non-final local variables? Answer: No, a lambda expression cannot access non-final or non-effectively final local variables. This is because the variables accessed by a lambda expression must be effectively final, meaning they are not modified after initialization. 14. Can a lambda expression mutate the value of a variable from its enclosing scope? Answer: No, a lambda expression cannot mutate the value of a variable from its enclosing scope, even if the variable is effectively final. 15. What is the target type of a lambda expression? Answer: The target type of a lambda expression is the functional interface to which the lambda expression is assigned or passed as an argument. 16. How do you pass a lambda expression as a method parameter in Java? Answer: You can pass a lambda expression as a parameter by defining the parameter type as a functional interface and then providing the lambda expression as the argument. 17. Can a lambda expression have multiple parameters? Answer: Yes, a lambda expression can have multiple parameters separated by commas. 18. What is a consumer in Java? Answer: A consumer is a functional interface with a single abstract method called 'accept'. It represents an operation that accepts a single input and returns no result. 19. What is a predicate in Java? Answer: A predicate is a functional interface with a single abstract method called 'test'. It represents a boolean-valued function that takes a single input and returns true or false. 20. What is the difference between a lambda expression and an anonymous class in Java? Answer: Lambda expressions are shorter and more concise than anonymous classes. They promote functional programming and make the code easier to read and maintain. 21. How are lambda expressions used with streams in Java? Answer: Lambda expressions are commonly used with streams in Java to perform operations on collections of data. They can be used to filter, map, or reduce data elements in a stream. 22. What is the syntax for a lambda expression with no parameters? Answer: If a lambda expression has no parameters, you can use empty parenthesis to indicate an empty parameter list. For example: () -> expression. 23. Can a lambda expression have a void return type? Answer: Yes, a lambda expression can have a void return type if the functional interface to which it is assigned or passed as an argument declares a void return type. 24. What is the purpose of the ellipsis (...) in a lambda expression? Answer: The ellipsis (...) allows a lambda expression to accept variable arguments, similar to how methods with variable arguments are defined. 25. What is the difference between a lambda expression and a method reference? Answer: A lambda expression provides a custom implementation for a functional interface's abstract method, while a method reference refers to an existing method that matches the functional interface's signature. 26. What is the use of the @FunctionalInterface annotation in Java? Answer: The @FunctionalInterface annotation is used to indicate that an interface is intended to be a functional interface. It is not required for a functional interface, but it helps prevent accidental addition of multiple abstract methods. 27. How do you create a lambda expression that takes two parameters? Answer: To create a lambda expression with two parameters, you can list the parameters separated by commas in the lambda expression. For example: (param1, param2) -> expression. 28. What is a binary operator in Java? Answer: A binary operator is a functional interface with a single abstract method called 'apply'. It represents an operation that takes two operands of the same type and returns a result of the same type. 29. What is the difference between lambda expressions and anonymous inner classes? Answer: Lambda expressions are less verbose and more expressive than anonymous inner classes. They do not require the use of the 'new' keyword and eliminate the need for explicit type declarations. 30. How do you assign a lambda expression to a variable in Java? Answer: You can assign a lambda expression to a variable of a functional interface type. The lambda expression must have the same parameter types as the abstract method in the functional interface. 31. What is the syntax for a lambda expression with a single parameter? Answer: If a lambda expression has a single parameter, you can omit the parentheses around the parameter. For example: parameter -> expression. 32. What is the role of the 'default' keyword in a functional interface? Answer: The 'default' keyword is used to declare a default implementation for a method in a functional interface. Default methods provide a way to add new methods to an interface without breaking backward compatibility. 33. How do you use a lambda expression to iterate over a collection in Java? Answer: You can use a lambda expression with the 'forEach' method to iterate over a collection in Java. The lambda expression is used to define the action to be performed on each element of the collection.
