In Java, what is the method to ensure that the size of the table matches the size of the row?

edit

There is no specific method in Java to ensure that the size of the table matches the size of the row. It is the responsibility of the programmer to ensure that the table dimensions match the size of the data being stored in the table. One way to ensure this is to use the length property of arrays to set the size of the table and ensure that the row data being added has the correct length. Another way is to use List or Set data structures which automatically adjust their size as data is added or removed.
