    1.Java的默认编码 
    java的src.zip包中的java.nio.charset.Charset类中defaultCharset()方法说明java的编码类型是有jvm的file.encoding参数决定的,如果未指定默认是UTF-8
    /**
    * Returns the default charset of this Java virtual machine.
    *
    * <p> The default charset is determined during virtual-machine startup and
    * typically depends upon the locale and charset of the underlying
    * operating system.
    *
    * @return A charset object for the default charset
    *
    * @since 1.5
    */
    public static Charset defaultCharset() {
    if (defaultCharset == null) {
    synchronized (Charset.class) {
    String csn = AccessController.doPrivileged(
    new GetPropertyAction("file.encoding"));
    Charset cs = lookup(csn);
    if (cs != null)
    defaultCharset = cs;
    else
    defaultCharset = forName("UTF-8");
    }
    }
    return defaultCharset;
    }
