Which of the following lines of code compile?

Choose all that apply

  • A. int i1 = 1_234;
  • B. double d1 = 1_234_.0;
  • C. double d2 = 1_234._0;
  • D. double d3 = 1_234.0_;
  • E. double d4 = 1_234.0;
  • F. None of the above.


A, E.

Note

Underscores are allowed as long as they are directly between two other digits.

This means options A and E are correct.

Options B and C are incorrect because the underscore is adjacent to the decimal point.

Option D is incorrect because the underscore is the last character.
