Imagine you are implementing a system that performs various mathematical operations. How would you use Lambda expressions to define various operations in a clean and efficient way?
- By creating a separate class for each mathematical operation and using the Lambda keyword to instantiate objects of these classes.
- By defining functional interfaces with abstract methods corresponding to each mathematical operation and implementing them using Lambda expressions.
- By using nested Lambda expressions within each other to perform mathematical operations.
- By using traditional method declarations and avoiding Lambda expressions for mathematical operations.
In Java, you can use Lambda expressions to implement functional interfaces with a single abstract method. For mathematical operations, you can define functional interfaces, such as BinaryOperator, and use Lambda expressions to implement these interfaces concisely and efficiently. This approach enhances code readability and allows you to pass behavior as data, making your code more modular.
When reading from a file using a FileReader, it's often wrapped with a ________ to increase efficiency.
- BufferedReader
- FileBufferReader
- FileWriter
- InputStreamReader
When reading from a file, wrapping a FileReader with a BufferedReader is a common practice in Java. BufferedReader buffers the input, reducing the number of reads from the file and thus increasing efficiency.
Which of the following data structures does not allow duplicate elements?
- ArrayList
- HashSet
- LinkedList
- TreeMap
The HashSet data structure in Java does not allow duplicate elements. It is implemented using a hash table and ensures that all elements are unique by using the hashing mechanism. ArrayList and LinkedList can contain duplicate elements, while TreeMap allows duplicates based on keys.
What will be the output of the executeQuery() method in JDBC?
- A boolean indicating success or failure.
- Nothing; it doesn't return any value.
- The number of rows affected.
- The result of the SQL query execution.
The executeQuery() method in JDBC returns a ResultSet object, which contains the result of the SQL query execution. This ResultSet can be used to retrieve and manipulate the query results. The other options are incorrect as they do not accurately describe the output of this method.
The ________ class provides a tunable, flexible thread pool.
- ExecutorService
- Runnable
- Thread
- ThreadPoolExecutor
The ThreadPoolExecutor class in Java provides a tunable, flexible thread pool. It allows you to customize various aspects of thread pool behavior, such as the number of threads and task scheduling.
