Quick Answer
The answer is `String names[] = {"A", "B"};` and `new String[]{"A", "B"}` as part of a combined declaration and initialization. These are valid because Java allows the array initializer syntax with curly braces `{}` either directly after the variable name or using the `new` keyword with an anonymous array, both of which create and populate the array in a single statement. On the Oracle Java Foundations 1Z0-811 exam, this tests your understanding of the distinction between declaration, instantiation, and initialization—a common trap is thinking you can use the `new` keyword with a size in brackets alongside an initializer, like `new String[2]{"A", "B"}`, which is invalid. The exam often presents options that mix these syntaxes to catch candidates who confuse array creation with array declaration. A solid memory tip: when you see curly braces, think "immediate values"; when you see `new` with a size, think "empty container." For the 1Z0-811, remember that the size is inferred from the initializer, so never specify both.
This 1Z0-811 practice question tests your understanding of arrays and methods. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO are valid ways to declare and initialize an array of Strings?
String[] names = {"A", "B"}[];
Why wrong: Invalid syntax with brackets after initializer.
String names[] = new String[2];
Why wrong: Valid but initializes with nulls, not with values.
String[] names = new String[]{"A", "B"};
Valid anonymous array creation.
String[] names = {1, 2};
Why wrong: Type mismatch; ints cannot be assigned to String array.
String names[] = {"A", "B"};
Valid C-style declaration with initializer.
Answer choices
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"};
Option C is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
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];
Why it's wrong here
Valid but initializes with nulls, not with values.
String[] names = new String[]{"A", "B"};
Why this is correct
Valid anonymous array creation.

String[] names = {1, 2};
Why it's wrong here
Type mismatch; ints cannot be assigned to String array.
String names[] = {"A", "B"};
Why this is correct
Valid C-style declaration with initializer.

Common exam traps
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.
Detailed technical explanation
In Java, array initializers like `{"A", "B"}` can only be used in a declaration statement (e.g., `String[] names = {"A", "B"};`) or with the `new` keyword (e.g., `new String[]{"A", "B"}`). The `new` form is required when the array is passed as an argument to a method or assigned to a variable that was already declared. Under the hood, the JVM allocates contiguous memory for the array and stores references to the String objects from the constant pool.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 1Z0-811 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which of the following correctly declares and initializes an array of strings with the elements "A", "B", and "C"?
easyWhy D: Option D is correct because in Java, an array can be declared and initialized using the array initializer syntax with curly braces `{}` directly after the declaration, as in `String[] arr = {"A", "B", "C"};`. This is a shorthand that implicitly creates a new array object with the specified elements, and it is only valid in a declaration statement (not in an assignment to an already-declared variable).
Variation 2. Which of the following is not a valid array variable declaration in Java?
easyWhy A: Option A is correct because `int arr;` declares a simple integer variable, not an array. In Java, an array variable declaration must include square brackets ([]) to indicate the variable is an array type. Without brackets, the variable is a primitive or reference type, not an array.
Variation 3. Which two of the following are valid ways to declare and initialize an array of integers? (Select two.)
easyWhy B: Options A and B are valid. Option A creates an array with default values (0). Option B creates an array with specified values. Option C is invalid because you cannot specify both size and initializer. Option D has invalid syntax. Option E assigns an int to an int array variable.
