You have to construct an object of the type of the first class (which you are not mentioning) inside Database.

class Database{

void insert(ArrayList lst){
.....//your business  logic
}

void invokeInsert(){
YourClass x = new YourClass();
insert(x.getList());
}

class YourClass{
private ArrayList list;

public ArrayList getList(){
return list;
}
}

If the insert method is static in the class Database then you could simply pass like this Database.insert(empList); or you can create an object and pass like this. Database db = new Database() db.insert(empList);

just pass the argument as you would pas any other argument.

insert(empList)

and declare insert as insert(ArrayList<Type> empList)
