Roll a six-sided die 6000 times in Java
In order to roll a six sided die 6000 times in Java, we need to the nextInt() statement with decision making statements.
The nextInt() method returns the next random integer value from this random number generator sequence.
Declaration − The java.util.Random.nextInt() method is declared as follows −
public int nextInt()
Let us see a program to roll a six sided die 6000 times −
Example
import java.util.Random;
public class Example {
public static void main(String args[]) {
Random rd = new Random(); // random number generator
int freq[] = new int[6]; // creating an array to compute frequency of each face
int val;
int chance = 1;
// rolling the dice 6000 times
while(chance <= 6000){
val = 1 + rd.nextInt(6); // generates integers from 1 to 6
switch (val) {
case 1:
++freq[0];
break;
case 2:
++freq[1];
break;
case 3:
++freq[2];
break;
case 4:
++freq[3];
break;
case 5:
++freq[4];
break;
case 6:
++freq[5];
break;
}
chance++;
}
for(int i = 1; i <= 6; i++){
System.out.println("Side: " + i + "-> Frequency : " + freq[i - 1]);
}
}
}Output
Side: 1-> Frequency: 987 Side: 2-> Frequency : 971 Side: 3-> Frequency : 1057 Side: 4-> Frequency : 979 Side: 5-> Frequency : 982 Side: 6-> Frequency : 1024
