I would like to store the value randomly generated and called into p .randomParticipation() is there a way?

public class App {
 
    public static void main(String[] args) {
        Group g1 = new Group("The Killers");
        Student st1 = new Student("Zack", "Zando");
        Student st2 = new Student("Chris", "Mario");
        Student st3 = new Student("Frank", "Smith");
        Student st4 = new Student("Nick", "Do");
        Behavior b1 = new Behavior();
        Participation p = new Participation();
        
        System.out.println("The group Name is: " + g1.groupName);
        System.out.println(g1.groupName+" are "+st1.firstName+" "+st2.firstName+" "
            + ""+st3.firstName+" "+st4.firstName);
        b1.randomBehavior();
        //System.out.println("The student " + st3.firstName + " is "+b1.randomBehavior());
        System.out.println(g1.groupName+" members have the following participation "
            +    st1.firstName +" "+ p.randomParticipation()
            +" "+st2.firstName +" "+ p.randomParticipation()
            +" "+st3.firstName +" "+ p.randomParticipation()
            +" "+st4.firstName +" "+ p.randomParticipation());
        System.out.println("The sum of the total participation is: ");
    }
}

public class Group {
    String groupName;
    String participation;
      
    public Group(String theGroupsName){
        groupName = theGroupsName;
    }
    private String groupName()
    {
        return groupName;
    }
    private String groupParticipation()
    {
        return participation;
    }
}

public class Student {
    String firstName;
    String lastName;
    String participation;

    public  Student(String theStudentName, String theStudentLastName){
        firstName = theStudentName;
        lastName = theStudentLastName; 
    }
}

import java.util.Random;
 
public class Behavior {
    private final Random r = new Random();
 
    private final String[] behaviour = new String[] {
       "practicing Jiu Jitsu.",
       "reading Java.",
       "kissing the girlfriend.",
       "walking the Dogs.",
       "making the bed"     
    };
 
    public String randomBehavior() {
        
        return behaviour[ r.nextInt(5) ];
    }
}

import java.util.Random;
 
public class Participation {
    private final Random r = new Random();
 
    private final int[] participation = new int[] {
          1,2,3,4,5,6,7,8,9,10 
    };
    
    public int randomParticipation() {
        
        return participation[ r.nextInt(10) ];
    }
}

May be you can create an Utility class and create a random Number generator in it. Then call it from any class you wanted to use and store the result in a variable.

public final class Utility {
	
	private static final Random RANDOM = new Random();
	
	private Utility() {
		
	}
	
	public static int generateRandomInt(int range) {
		return RANDOM.nextInt(range);
	}
	
}
}
