Java OCA OCP Practice Question 540

Question

Which of the following are true?

Choose all that apply

  • A. A local variable of type boolean defaults to null.
  • B. A local variable of type float defaults to 0.
  • C. A local variable of type Object defaults to null.
  • D. A local variable of type boolean defaults to false.
  • E. A local variable of type boolean defaults to true.
  • F. A local variable of type float defaults to 0.0.
  • G. None of the above. 


G.

Note

Option G is correct because local variables do not get assigned default values.

The code fails to compile if a local variable is not explicitly initialized.

If this question were about instance variables, options D and F would be correct.

A boolean primitive defaults to false and a float primitive defaults to 0.0.
