Java Standard Library and Collections Framework

In this chapter, we’ll explore the powerful features provided by the Java Standard Library and Collections Framework. We’ll learn about key classes and interfaces that are essential for working with data structures, strings, files, and other common tasks in Java programming. The topics covered in this chapter include:

• Strings and StringBuilder: Learn how to work with strings, perform common operations like concatenation, and understand the difference between String and StringBuilder.

• File Input and Output: Discover how to read and write files in Java, including text and binary files, using various techniques provided by the Java Standard Library.

• Date and Time Handling: Understand the basics of handling date and time in Java using the java.time package, which provides classes like LocalDate, LocalTime, and ZonedDateTime.

• Collections Framework: Dive into the Java Collections Framework and learn how to use its core interfaces and classes, including List, Set, Map, and their respective implementations.

• Generics: Enhance your knowledge of Java by learning about generics, which enable you to create flexible and type-safe data structures and algorithms.

Throughout this chapter, you’ll gain a solid understanding of the Java Standard Library and Collections Framework, which will prove invaluable as you continue to develop your Java programming skills.
