What method can be used to print container objects nicely?

printDetails
toString
print
display

The correct answer is: toString

The toString method is commonly used to convert a container object into a string representation for printing. This method is part of the Object class and can be overridden by a subclass to output information in a specific format. Option A, printDetails, is not a standard method and may not be recognized by the compiler. Option C, print, and option D, display, may also work for printing, but they are not the recommended method for printing container objects as they do not have the same functionality and flexibility as the toString method.
