遇到困難

我照著網站步驟做，出現了
'javac' is not recognized as an internal or external command, operable program or batch file 的訊息

在網站我發現
If you encounter problems with the instructions in this step, consult the Common Problems (and Their Solutions).
剛好在裡面找到了我的問題
裡面寫到
If you receive this error, Windows cannot find the compiler (javac).
Here's one way to tell Windows where to find javac. Suppose you installed the JDK in C:\jdk6. At the prompt you would type the following command and press Enter: C:\jdk6\bin\javac HelloWorldApp.java If you choose this option, you'll have to precede your javac and java commands with C:\jdk6\bin\ each time you compile or run a program. To avoid this extra typing, consult the section in the JDK 6 installation instructions.

在阿莫的網站發現了找到程式路徑的方法
但是學校電腦權限限制實在太多
讓我用了許久
由於C碟權限太多於是我複製到D碟
再照著解決步驟把記事本複製到bin資料夾就解決了
