As an *exercise*, might also want to do the formatting manually?
... by using String .indexOf('.') and .length() methods to determine how
many charaters after the decimal point, then add the append the appropriate
number of zeros to give you two decimal places. For alligning columns,
probably need to use .length() on individual strings to determine how many
spaces to use in padding to get column alignment.
