Explain the features of Java 8.

Question

Accepted Answer

Java 8 introduced significant features like lambdas, streams, and the new Date-Time API, enhancing productivity and code readability.

Lambda Expressions: Enable concise representation of functional interfaces. Example: (a, b) -> a + b.
Streams API: Facilitates functional-style operations on collections. Example: list.stream().filter(x -> x > 10).collect(Collectors.toList()).
Default Methods: Allow interfaces to have methods with implementations. Example: interface MyInterface { default void myMethod() { ... } }
New Date-Time API: Provides a comprehensive and standardized way to handle dates and times. Example: LocalDate.now(), LocalDateTime.now().
Optional Class: Helps in avoiding null references. Example: Optional name = Optional.ofNullable(getName());

Accepted Answer

Java 8 has introduced forEach method in java.lang.Iterable interface so that while writing code we focus on business logic. The forEach method takes java.util.function.Consumer object as an argument, so it helps in having our business logic at a separate location that we can reuse.
