1Z0-829 Handling Exceptions Practice Question

Exhibit

Refer to the exhibit.

Compilation output:
Error: unreported exception java.io.IOException; must be caught or declared to be thrown
  at Test.main(Test.java:5)

Given the exhibit showing a compilation error at line 5 of Test.java, which of the following code fragments could be at that line?

⚠ Common exam trap

The trap here is that candidates often forget that checked exceptions must be handled or declared, and mistakenly think any code that throws an exception will compile as long as it is inside a method, ignoring the compiler's requirement for checked exception handling.

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

✓

FileInputStream fis = new FileInputStream("test.txt");

The code at line 5 is a checked exception (FileNotFoundException) that must be handled or declared. The compilation error indicates that the method containing line 5 does not handle or declare this checked exception, which is required by the Java compiler.
