1Z0-829 Controlling Program Flow Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  Step 1: Declare and initialize resources in the try-with-resources parentheses. Step 2: Use the resources in the try block. Step 3: Resources are automatically closed in reverse order of declaration.

  Why this is correct

  This is the correct order because try-with-resources requires resources to be declared in the try header, then used in the try block, and they are closed automatically in the reverse order of their declaration to handle dependencies correctly.

• ✗

  Step 1: Use resources in try block. Step 2: Declare resources in try-with-resources. Step 3: Resources are closed in declaration order.

  Why it's wrong here

  This is incorrect because resources must be declared before use, and they are closed in reverse order, not declaration order.

• ✗

  Step 1: Declare resources in try-with-resources. Step 2: Close resources manually in a finally block. Step 3: Use resources in try block.

  Why it's wrong here

  This is incorrect because try-with-resources automatically closes resources; a manual finally block is not needed and using resources before closing is wrong.

• ✗

  Step 1: Use resources in try block. Step 2: Declare resources in try-with-resources. Step 3: Resources are closed automatically in declaration order.

  Why it's wrong here

  This is incorrect because resources must be declared before use, and the automatic closure order is reverse of declaration, not the same order.
