Help with random number?

[getmegetme26]

hi i am trying out random numbers but stuck on something, please can someone help?

i have got a simple program that gives out random names, when i try to output several at the same time they come out the same. can i change it?

package coral;

public class namegen {
	public static void main(String args[]) {
		String[]names;
		names = new String[10];
		names[0] = "ben";
		names[1] = "john";
		names[2] = "chris";
		names[3] = "matt";
		names[4] = "jack";
		names[5] = "alex";
		names[6] = "patric";
		names[7] = "sam";
		names[8] = "mike";
		names[9] = "andy";
		
		int num = (int) (Math.random()*10);
		
		System.out.println("My name is " + names[num]);
		System.out.println("My name is " + names[num]);
		System.out.println("My name is " + names[num]);
		System.out.println("My name is " + names[num]);
	}

}
