Question

difference between..(int)2.56 and Math.random(2.56)....in java​

Answer 1

Answer:

The (int) casts the double result of Math.random() to an integer. So (int) Math.random() always is zero, because random() returns a number greater than or equal to 0.0 and less than 1.0

int i = (int)Math.random();

double d =  Math.random();

System.out.println(i);

System.out.println(d);

If you need integer randoms, you need first to multyply the result of random

int factor = 100;

i = (int)(Math.random() * factor);

System.out.println(i);
