如果批处理编辑中的/ else命令语法

Question

如何在此代码中添加ELSE部分，以便在找不到javac.exe时，它会提供相应的找不到JDK 消息？

 FOR /R "C:\Program Files" %%a IN (.) DO (
        IF EXIST "%%~a\javac.exe" ECHO You Have The Java Dev Kit Ignore 

    Option 4) 

Answer 1

您可以在IF语句中添加一些括号，然后添加ELSE

IF EXIST "%%~a\javac.exe" (
        ECHO You Have The Java Dev Kit Ignore 
    ) ELSE (
        ECHO Cannot Find JDK
    )

Answer 2

  IF EXIST "%%~a\javac.exe" (ECHO You Have The Java Dev Kit Ignore) ELSE ( do something else )
