java – What does it mean to assign Math.random() > 0.5 to a variable?

Question:

What does it mean Math.random() > 0.5; in a boolean ? Here's an example:

class Pro {

    public static void main(String[] args) {

        int numero = 10;
        boolean[] array = new boolean[numero];
        for(int i= 0; i< array.length; i++) {
           array[i] = Math.random() > 0.5;
           System.out.print(array[i] + "\t");
        }
    }
}

Answer:

Math.random() will generate a value between 0 and 0.999999 (tends to limit 1, but doesn't reach 1).

Logo your code snippet:

array[i] = Math.random() > 0.5;

It is checking if the value generated by the random function is greater than 0.5

If it is greater, it sets true for that position of the array. Otherwise, set to false .
