What is String Class In Java?

In Java, the String class represents a sequence of characters and is used to create and manipulate string data. Strings are immutable, meaning once created, their values cannot be changed. The String class provides various methods for string manipulation, such as length, substring, concatenation, and searching. Strings can be created using string literals or the String constructor. String objects are widely used for text processing and are fundamental in Java programming due to their versatility and ease of use.

Advantages of String Class In Java?

The Java String class offers several advantages, including:

1. Immutability: Strings are immutable, making them thread-safe and reducing bugs related to changing values.
2. Built-in Methods: Provides numerous methods for manipulation, such as substring, concatenation, and searching.
3. Memory Efficiency: Utilizes string pooling to optimize memory usage for identical strings.
4. Easy Comparison: Provides methods like .equals() and .compareTo() for straightforward string comparison.
5. Integration: Works seamlessly with other Java classes, collections, and APIs.

Overall, the String class enhances code efficiency and readability.
