How Can One Check If A String Is Empty Or Null In Java?

To check if a string is empty or null in Java, you can use the following code:

String str = "Hello World";

if (str == null || str.isEmpty()) {
    // String is either null or empty
    System.out.println("String is empty or null");
} else {
    // String is not empty or null
    System.out.println("String is not empty or null");
}

In this code, we use the isEmpty() method to check if the string is empty and the null-check (str == null) to check if the string is null. If either of these conditions is true, we consider the string as empty or null.
