Java OCA OCP Practice Question 906

Question

Which of these array declarations is not legal?

Choose all that apply

  • A. int[][] scores = new int[5][];
  • B. Object[][][] cubbies = new Object[3][0][5];
  • C. String beans[] = new beans[6];
  • D. java.util.Date[] dates[] = new java.util.Date[2][];
  • E. int[][] types = new int[];
  • F. int[][] java = new int[][]; 


C, E, F.

Note

Option C uses the variable name as if it were a type, which is clearly illegal.

Options E and F don't specify any size.

Although it is legal to leave out the size for later dimensions of a multidimensional array, the first one is required.

Option A declares a legal 2D array.

Option B declares a legal 3D array.

Option D declares a legal 2D array.
