You can not typecast int to string try below code.

jTextField1.setText(String.valueOf(l.getCode()));

Use

   Integer.toString(l.getCode);

Try something like this:

Integer.valueOf(l.getCode()).toString()

You cannot convert int simple type to String object.

[`String.valueOf(int)`](http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#valueOf(int)) or [`Integer.toString(int)`](http://docs.oracle.com/javase/7/docs/api/java/lang/Integer.html#toString%28int%29) is simpler. – Mark Rotteveel Mar 05 '13 at 11:38

This should be what you are looking for:

jTextField1.setText(String.valueOf(l.getCode()))

You should innest properly the brackets... as it is now it will not compile – araknoid Mar 05 '13 at 11:25
@araknoid yes it will. The only difference between this answer and yours is this one has a line terminator. – ldam Mar 05 '13 at 11:39

There are three ways you convert an integer to string firstly using the built-in converter,

jTextField1.setText("" + l.getCode())

Secondly you could use the static method toString(int) of the Integer class,

jTextField1.setText(Integer.toString(l.getCode()))

You could also use a formatter but this in not recommended as it just makes the code cumbersome and difficult to understand.

jTextField1.setText(String.format("%d", l.getCode()))
