Re: Array type of structure with different types in different columns
Theoretically, a 2d array, but that would be messy. I would suggest making each "row" an object, which has values for col1, col2, and col3, and then putting the rows in an array. That would be the cleanest solution.

Re: Array type of structure with different types in different columns
Rather than using parallel arrays to store data, use a CLASS. A class might be structured something like:
public class MyDataStructure { // instance variables String columnOne; double columnTwo; int columnThree; // a constructor that sets each instance variable public MyDataStructure( String columnOne, double columnTwo, int columnThree ) { this.columnOne = columnOne; this.columnTwo = columnTwo; this.columnThree = columnThree; } // end constructor } // end class MyDataStructure
