Thread: Printing many random names from an array

In this code I create first a list with some names and then print them randomly:

package testrandom;
 
 
public class TestRandom {
 
 
public static void main(String[] args) {
String [] name={"Bob","Joe","Max","Alfred","Mat"};
int min =0;
int max= name.length;
int random_int = (int)Math.floor(Math.random()*(max-min+1)+min);
System.out.println(name[random_int]);
 
}
 
}

This code prints only one name everytime I run it. Now if I want to have for exemple 3 random names from that list each time, how should I modify my code ?!

I tried with this but failed:

package testrandom;
 
 
public class TestRandom {
 
 
public static void main(String[] args) {
String [] name={"Bob","Joe","Max","Alfred","Mat"};
int min =0;
int max= name.length;
 
for (int i=0; i<4;i++)
///System.out.println("Random value in int from " +min+"to "+max+" : ");
int random_int = (int)Math.floor(Math.random()*(max-min+1)+min);
//System.out.println(random_int);
System.out.println(name[random_int]);
 
}
 
}

failed

Please explain what that means. What happened when the code was compiled and executed?
Why did it fail?

Please edit your post and wrap your code with code tags:

[code]
**YOUR CODE GOES HERE**
[/code]

to get highlighting and preserve formatting.

What happened to the code's indentations? All the statements start in the first column. That makes the code harder to read and understand. For example it is hard to see what statements are inside of the for loop and what statements follow the loop.

What happens when you compile and execute the code? Copy the output and paste it here. Add some comments to the output saying what is wrong with it.
