请问下大家java中有画点的方法吗？这个方法在哪个类中啊？

楼主，对不起啦
更正一下我提供的方法也可以，但是jdk提供了有。请您看：java.lang.Object
java.awt.geom.Point2D
java.awt.Point
在这里了

没错啊java.lang.Object
java.awt.geom.Point2D
java.awt.Point这是java提供的画点类啊

point哪里提供可以画点的动作？

我在想所有的图形都是由系统函数调用一个一个点然后汇集而成的
我现在想找到fillrect（）方法实现的源代码

一下摘自jdk文档提供的代码

jdk只是提供了描述一个点的类Point，而没有画一个点的方法，在VC中就有画一个点的方法

好吧，那说说java虚拟机是如果画一个图形的？难道是直接调用操作系统的图形函数？？？
那它怎么实现夸平台啊？？？？

调试易

请问下大家java中有画点的方法吗？这个方法在哪个类中啊？
