What are some common string methods in Java?

In Java, common string methods include length(), charAt(), substring(), indexOf(), and toLowerCase(). Would you like examples?

Yes, please provide examples for each of those methods.

Sure!

1. length(): Returns the length of the string.
2. charAt(int index): Returns the character at the specified index.
3. substring(int beginIndex, int endIndex): Returns a substring from the string.
4. indexOf(String str): Returns the index of the first occurrence of the specified substring.
5. toLowerCase(): Converts the string to lowercase.

Can you show me a code snippet that uses these methods?

Absolutely! Here's a simple code snippet:

public class StringMethodsExample {
    public static void main(String[] args) {
        String str = "Hello, World!";
        System.out.println("Length: " + str.length());
        System.out.println("Character at index 1: " + str.charAt(1));
        System.out.println("Substring (0, 5): " + str.substring(0, 5));
        System.out.println("Index of 'World': " + str.indexOf("World"));
        System.out.println("Lowercase: " + str.toLowerCase());
    }
}

Thanks! That was really helpful.
