I am a newbie at java and I’m attempting to do a program to introduce myself.
Beneath is my script.

class Description 
{ 
// Occasion variable 
non-public String identify, nationwide, dob;
non-public ArrayList<String> hobbies = new ArrayList<String>();  

public Description()
{

}

// Different Constructor 
public Description(String identify, String nationwide, String dob)
{
    this.identify = identify; 
    this.nationwide = nationwide;
    this.dob = dob;
}

// Copy Constructor 


// Accessor Methodology
non-public String getname()
{
    return identify; 
}

non-public String getnational()
{
    return nationwide; 
}

non-public String getdob()
{
    return dob;
}

non-public ArrayList geHobbies(){
    return hobbies;
}

// Mutator Methodology
public void setHobbies(ArrayList hobbies)
{
    this.hobbies = hobbies;
}



public void printInfo()
{   
    System.out.println("My Data");
    System.out.printf("Identify: %spercentn", getname()); 
    System.out.printf("Nationwide: %spercentn", getnational());
    System.out.printf("Date of beginning: %spercentn", getdob());

    System.out.printf("I've %d hobbies %n", hobbies.dimension());
    System.out.printf("  1: %spercentn", hobbies.get(0));
    System.out.printf("  2: %spercentn", hobbies.get(1));
}

}

class Lab_1 
{

    public static void important (String [] args)
    {

        Description ds = new Description("Ron ", "Singapore",  "01-01-2020"); 
        ArrayList <Description> hobbies = new ArrayList <Description> ();
        hobbies.add("Finding out");
        hobbies.add("Coding");

        ds.printInfo();

    }
}

Nevertheless I obtained “error: incompatible varieties: String can’t be transformed to Description” after I tried to run the script. Can any knowledgeable on the market information me on how I can resolve this difficulty. Thanks! I’m additionally required to create one other arraylist name needs, and embody four needs. whereas I am nonetheless caught at hobbies, I am unable to proceed and work on the opposite arraylist.
