Answer 1

your main seems not right
public static void main(String[]args)

for buffer reader you can wrap them in try catch
try{
//readhere
}catch(IOException ex){
// do something if failed
}

Answer 2

Or you can use the throws clause-

public static void main(String[] args)
throws Exception {
// Code goes here
}
