      The array elements are assigned default values for their type, in this case, 0. For a String array created using new String[3], each element would contain null. b.length is the number of elements in array b. In this case, b.length is 3. Note that length is a variable, not a function; b.length() is syntactically incorrect.

      Each row in a two-dimensional array is itself an array. So, the rows can have different lengths. Such an array is known as a ragged array. If you don’t know the values in a raged array in advance, but know the sizes, say the same as before, you can create a ragged array using the syntax that follows:
