1Z0-811 Arrays and Methods Practice Question
Which TWO are valid ways to declare and initialize an array of Strings?
⚠ Common exam trap
Oracle often tests the distinction between array declaration syntax and the two valid initialization forms, trapping candidates who think `new String[2]` initializes with given values or that `{"A", "B"}[]` is a valid shortcut.
Answer choices
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
✓
String[] names = new String[]{"A", "B"};
It uses the valid syntax `new String[]{"A", "B"}` to both declare and initialize a String array in a single statement. This is the standard way to create an array with an anonymous array initializer when the declaration and initialization are combined.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
String[] names = {"A", "B"}[];
Why it's wrong here
Invalid syntax with brackets after initializer.
- ✗
String names[] = new String[2];

String[] names = new String[]{"A", "B"};
Why this is correct
Valid anonymous array creation.
- ✗
String[] names = {1, 2};
