Help With Generating Random Initial Board For Game Of Life

[theYe]

So right now, my part is to create the initial generation for Game of Life, randomly. It's hard for me to tell if I am heading in the right direction without writing the rest of the code to see if it works. Can anyone give me some input on what I shouldn't be doing or if it needs to be fixed, thanks.

private boolean[][] world;
 
 
 
private static void createRandomWorld {
 
boolean[][] world = new boolean[10][10];
		for(int row = 0; row < world.length; row++ ){
			for(int col = 0; col < world[row].length; col++ ){
				world[row][col] = (Math.random() < 0.40);
            if (world[row][col] == 0)
                    System.out.print("0");
                else
                    System.out.print("x");
           }
             }
             }
