I think the method1 and the method2 is the same.
Why the compiler complains "missing return statement" in the method2?
Thanks.
public class ExceptionHandlingTest {
public static void main(String[] args) throws Exception {
System.out.println(method1());
}
public static String method1() throws Exception{
try{
return "method1";
}catch(Exception e){
throw new Exception();
}finally{
}
}
public static String method2() throws Exception{
try{
return "method2";
}catch(Exception e){
method3();
}finally{
}
}
public static void method3() throws Exception{
throw new Exception();
}
}

In order for the compiler to prove definitively that the two are
equivalent, it would have to inline method3, and inline any methods it
calls, and so on, and so on. All the compiler sees when its compiling
method2 is a call to method3; it doesn't know or care at that point
exactly what method3 does.
