[問題] OCJP SE6 - command-line invocations
public class Prac {
public static void main(String[] args) throws Exception{
int x = 6;
Prac p = new Prac();
p.doStuff(x);
System.out.println(" main x = " + x);
}
void doStuff(int x){
System.out.println(" doStuff x = " + x++);
}
}
And the command-line invocations:
javac Prac.java
java Prac 5
--------------------------------------------------------------------
What is the result?
Ans:
B. An exception is thrown at runtime.
我自己原本是寫
C. doStuff x = 6 main x = 6
想請要一下, 是哪邊會丟出 runtime exception? 且是哪種exception?
我有試著自己跑過這個code, 但沒有看到錯誤訊息, 於是仍然困惑著
