SCJP題庫第092題

Given a correctly compiled class whose source code is:

1. package com.sun.sjcp;

2. public class Commander {

3.   public static void main(String[] args) {

4.     // more code here

5.   }

6. }

Assume that the class file is located in /foo/com/sun/sjcp/, the current directory is /foo/, and that the classpath contains "." (current directory).

Which command line correctly runs Commander?

A. java Commander

B. java com.sun.sjcp.Commander

C. java com/sun/sjcp/Commander

D. java -cp com.sun.sjcp Commander

E. java -cp com/sun/sjcp Commander

 

Ans: B

 

解說:

設類別檔放在/foo/com/sun/sjcp/中，目前目錄是/foo/，classpath為一個’.’，那一個指令可以執行類別Commander?

程式碼中宣告Commander 是在套件com.sun.sjcp下，執行即以java com.sun.sjcp.Commander來執行
