，所以您有一个宽度为i的矩形.很好，将其存储在成员变量中，并使用该成员设置宽度.
然后，只需将值j添加到值i-并更新canvas(！).这真的很重要，因为您可以更改很多值，但是它们只会在您repaint()时显示.
so you have a rectangle with a width i. Fine, store that in a member variable and set the width by using that member.
Then, simply add value j to value i - and update your canvas(!). That is really important, as you can change values around pretty much, but they will only show up when yourepaint().
