Scala Try Catch Finally:
在Java中返回值优先级顺序：finally最高， try，catch 选其一，try中抛异常，返回catch，不抛异常，返回try，。
public class ExceptionDemo { public static void main(String[] args) { System.out.println(callMD()); } public static int callMD() { try { // throw new Exception(); return 1; } catch (Exception e) { return 2; } finally { return 3; } } }
Scala模仿Java:
object ExceptionCatchDemo extends App {
def testTryCatchFinally: Int = {
try { throw new Exception();} catch { case _ => return 2 } finally { return 3 }
}
println(testTryCatchFinally)
}
运行结果：3
