What is String Class Methods Java?

In Java, the String class provides several methods for string manipulation. Key methods include:

• length(): Returns the length of the string.
• charAt(int index): Returns the character at the specified index.
• substring(int beginIndex, int endIndex): Extracts a portion of the string.
• indexOf(String str): Finds the index of a substring.
• toLowerCase(), toUpperCase(): Converts the string to lower or upper case.
• trim(): Removes leading and trailing whitespace.
• equals(Object obj): Compares two strings for equality.
• concat(String str): Appends the specified string.

These methods facilitate various string operations.

Advantages of String Class Methods Java?

The String class methods in Java offer several advantages:

1. Immutability: Strings are immutable, ensuring thread safety and reducing bugs.
2. Convenience: Methods like substring(), indexOf(), and toUpperCase() simplify common tasks.
3. Enhanced Readability: Method chaining and expressive names make code more readable.
4. Performance: String methods are optimized for efficiency, improving execution time for string manipulations.
5. Built-in Utility: Extensive built-in methods reduce the need for custom implementations, saving development time.

Overall, these methods facilitate easier and safer string handling in Java applications.
