Question

I am trying to have a 2D Array that is 16 rows by 11 columns where row 0, column 3 is a reference to another array that is a single dimension array. How do i go about doing this? I already have both arrays where the single dimension array is a char array(although i could make it a string array if i wanted) and the 2D array is a string array. The rest of the 2D Array is filled with plain strings for each elements with the exception of row 0, column 3 which i want it to be the single dimension array.

Answer 1

Object[] arrayToReference = ...;
Object[][] arrayWithReference =  new Object[] { ..., arrayToReference, ...};

This should work; just reference the array and it should change as the original changes

Here’s an example code snippet:

    Object[] array = new Object[] { "Test!" };
    Object[][] arrayArray = new Object[][] { array };
    System.out.println("Before: " + arrayArray[0][0]);
    array[0] = "Test2!";
    System.out.println("After: " + arrayArray[0][0]);

which has the following output:

Before: Test!
After: Test2!
