my problem in main when i enter choice 2 and enter name and other information i save them in setname method
in choice 3 when i call getname method it says unassigned which is the default value but it's supposed to say the name that i entered can you tell me how to fix this

Try doing some debugging by adding some println statements that show the values of the variables as they are changed.

Make sure that there is only one object being used. For example are you calling the set method for one object and calling the get method with another object.

The scope of a name is only within the immediate surrounding {} brackets. Eg the Patient variable declared on line 335 has its scope from 331 to 376. As soon as you go outside that scope the variable is discarded.
So although you create a patient on lines 335 onwards that patient is discarded before you go round the loop again. Simiularly on 380/381 - you create new patient there and discard it soon after.
You need a patient variable (or array?) declared where all the parts of your code can access it.
