这些路径意思听起来很糊涂，对不对？这很正常，大家都这样。怎么办？开发中把下列参数进行修改，看结果是不是自己期望的那个：
/** * <dt>java.version <dd>Java version number * <dt>java.vendor <dd>Java vendor specific string * <dt>java.vendor.url <dd>Java vendor URL * <dt>java.home <dd>Java installation directory * <dt>java.class.version <dd>Java class version number * <dt>java.class.path <dd>Java classpath * <dt>os.name <dd>Operating System Name * <dt>os.arch <dd>Operating System Architecture * <dt>os.version <dd>Operating System Version * <dt>file.separator <dd>File separator ("/" on Unix) * <dt>path.separator <dd>Path separator (":" on Unix) * <dt>line.separator <dd>Line separator ("\n" on Unix) * <dt>user.name <dd>User account name * <dt>user.home <dd>User home directory * <dt>user.dir <dd>User's current working directory */ System.out.println("java.home="+System.getProperty("java.home"));
