the order of the two numbers (1 and 2) that we put in the array is fixed. Please think of a way to randomize
such order after class.
This is my problem..
i can not do that.

public class SortGrid extends World
{
private static final int WIDTH = 400;

public SortGrid()
{
super( WIDTH, HEIGHT, 1 );
// create the network node
Node first = new Node();final int leftX = WIDTH/2;
addObject( first , leftX, 300 );
// end nodes
End ends = new End;
for ( int i = 0; i < ends.length; i++ ) {
End end = new End();
ends = end;
addObject( end, NUMBER_X + NUMBER_PADDING*i, HEIGHT-NUMBER_Y );
}
// create the connections
first.setDestinations( ends, ends );
final int randomNums = {1, 2};
final Number numbers = new Number;
// make the numbers
for ( int i = 0; i < NUM_POSITIONS; i++ ) {
final Number number = new Number( randomNums );
final int x = NUMBER_X + NUMBER_PADDING*i;
final int y = NUMBER_Y;
numbers = number;
addObject( number, x, y );
addObject( new Start(), x, y );
}
// set the number destinations
numbers.setDestination( first );
numbers.setDestination( first );
// paint ordering
setPaintOrder(
Number.class,
Node.class,
Position.class,
Start.class
);
}
}
this is my code
