Because Strings in Java are immutable.
That means methods like concat() do not change the original string, they return a new one. Since the result of str.concat(" world") isn't stored or reassigned, the original str remains "hello".

🎯 Java Tip: Always assign the result of string operations to a variable if you want the change to reflect!
