Determine output of the following program.
public class Test{
public static void main(String args[]){
System.out.println( Math.floor( Math.random( ) ) ) ;
}
}
public class Test{
public static void main(String args[]){
System.out.println( Math.floor( Math.random( ) ) ) ;
}
}A. 1.0
B. 10.0
C. 0.0
D. 0.5
Answer: Option C
Solution(By Examveda Team)
random() is a static method defined in Math class.
Syntax: static double random()
random() always return a value in the range 0.0 <= Math.random() <1.0 So, taking floor function of any number between above range always yield 0.0.
Ex: Math.floor(0.958127101241...) = 0.0
Math.floor(0.05684865565...) = 0.0
