i getting error on 'start' in (start + finish) @ bottom. way fix add "int start = inputfn.nextint();" below ' scanner inputfn = new scanner(system.in);' screws up. able fix before forgot how did it. please help.

public static void main(string eth[]){  system.out.println("please enter integer:"); scanner inputfn = new scanner(system.in);   if (inputfn.hasnextint()){ }else{ int start = inputfn.nextint(); system.out.print("play rules , enter integer");  }  system.out.println("please enter integer:"); scanner inputsn = new scanner(system.in); int finish = inputsn.nextint();  int answer = (start + finish); system.out.println(answer);   } } 

the if

if (inputfn.hasnextint()){ }else{   int start = inputfn.nextint();   system.out.print("play rules , enter integer"); } 

is kind of backwards. reading integer if there isn't one. , defining start variable inside if block why getting error.

something more like

int start = 0; if (inputfn.hasnextint()){   start = inputfn.nextint(); }else{   system.out.print("play rules , enter integer"); } 

would seem better.
