Define dynamically event handler in Java

Here's a way to solve this without using an event handler. See if this works for what you are doing.

First, instead of two arrays, let's use two 2D arrays that are m x 1 and n x 1.

int[][] array1 = new int[m][];
int[][] array2 = new int[n][];
for (int i = 0; i < m; i++)
    array1[i] = new int[] { /* your code */ ? 1 : 0 };
for (int i = 0; i < n; i++)
    array2[i] = array1[ /* your code */ ];

The first /* your code */ is your condition for choosing to put either 1 or 0 into each element of array1. The second /* your code */ is your method for deciding which element of array1 corresponds to each element of array2.

Now each element in array2 is also an element of array1, so when you update a value in one of the arrays from 0 to 1, it is also updated in the other array.

array2[7] = array1[3];
array1[3][0] = 0;
System.out.println(array2[7][0]); // prints "0"
array1[3][0] = 1;
System.out.println(array2[7][0]); // prints "1"
