实际上在System中存在一个setOut的方法来改变out的实际引用(out为一个常引用):这个方法是个native方法,可以绕过Java语言的访问控制机制,是个及其特殊的情况 static method: 使用场景: 1. 该方法并不关注类对象的状态,所有的参数都是由参数表指定,并不需要隐性参数this 2. 该方法只访问该类的静态字段。静态方法并...

可以的。类可以有内部类，具体问题。具体再追问。错误提示是说：非静态变量类型不能在静态上下文中引用。（1）你的；main方法是static的，即静态的。（2）如果你将类包含在里面的话，需要将printchar声明为静态的。才能在main方法中引用。首先
