Answer 6

You are passing string type value to switch but cases using of int type so not matches. Error
And you are not using or catching switch returned values so it can't output anything after removing error also. So print strings instead of just returning ... ( eg: "button 1" is incomplete statement)
@
also using 5 as dublicate values for cases..
Dublicate cases not allowed..
Hope it helps to correct it..
