In Java 8, streams use a technique called “lazy evaluation” to process data. Lazy evaluation means that a stream operation is not executed until it is absolutely necessary. This can…
In this post, we will see Java8 Streams Interview questions. What is the difference between a Stream and a Collection in Java 8 Stream represents a sequence of elements and…
Java streams are a powerful feature introduced in Java 8 that allow for functional-style programming and operations on data in collections. Some key features of Java streams include: Laziness: Stream…
We can implement a custom class that behaves like an array by creating a class that has an array as a private field, and implements the necessary methods to access…
In Java, a String is an immutable object that represents a sequence of characters. It means once a String is created, its value cannot be changed, any operation that appears…
