BTW: class cannot be run/executed. You can only execute methods, often of instance of the class — Marcin Orlowski

lname.setText(user.get("lname"));

It seems that user.get("lname") doesn't return a String, yet setText accepts String as parameter.

Try to converse it to a String, or call the toString method on the result.

(user.get("lname")).toString(); or "" + user.get("lname"); which is like how you did it in the other case: "Welcome "+user.get("fname")

this will sort your problem.

what are you trying to say

user4687376 Over a year ago

all of my other classes it can recognise the R package or class, however it this java file main.java it cannot resolve symbol r .

clean your project and see there might be some error inside one of your xml files which might be blocking generation of R

The error occured because user.get("lname") does not explictly return a String.

You should call toString() or better if your sure that this is a String declare it when you declare your hashmap HashMap<String, String> user = new HashMap<String, String>();

What is inside your hashmap. Obviously the keys are String. But what is the class of the values ? If all values are String you should change the declaration of your HashMap as i suggest in my answer. If not, are you sure the object you get use setText(user.get("lname").toString())
