Given method: static void change(String s) { s = "new"; } What is output of: String name = "original"; change(name); System.out.println(name);

⚠ Common exam trap

The trap here is that candidates mistakenly think Java passes objects by reference, leading them to believe the method's reassignment changes the original variable, when in fact only the local reference is modified.

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

"original"

Java passes object references by value. Inside the method `change`, the local variable `s` is reassigned to a new String object, but this does not affect the original reference `name` in the main method. Strings are immutable, so the original `name` remains "original".
