How to get the last character of a string in Java using substring with exmple?

You can get the last character of a string in Java using the `substring()` method. Here’s an example: Example:

public class LastCharacterExample {
public static void main(String[] args) {
String str = "Hello World!"; 

// Using substring() to get the last character
String lastChar = str.substring(str.length() - 1);

System.out.println("Last character: " + lastChar);
}
}

Explanation: - `str.length() - 1` gives the index of the last character. - `substring(str.length() - 1)` extracts the last character as a substring. Output:

Last character: !
