How can I generate and display 6 random numbers for the National Lottery in Java

How can I Write a luckyDip() method that uses repetition to generate and display 6 random numbers for the National Lottery? The display should be of the format:

Ball 1 = 23

Ball 2 = 16

…….etc

public class Lotto { int random = (int)(Math.random()*49)+1;

    //Test
public static void main (String args[]) {
    
    Lotto l=new Lotto();
    //l.luckyDip();
}

}
