Java Link list error message when executed @number

Whenever i run the method, i get an error which comes with as numbers

The following is what i have as my code.

public String getAccount()
{
   String s = "Listing the accounts";
    for(List l:lists)
     s+=" "+list.toString;
   Return s;
}

I get the following when i run this method:

List@some numbers

For the List class, i just have a constructor which appoints parsed variables into local variables.

DOes someone know what this means?

This means that you haven't overridden the toString method in your (apparently) custom List class. The default implementation (Object.toString) displays output like you show above:

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())

You should override toString in your custom classes, in order to provide the desired output.
