Method parameter Default Value

Sometimes we can use the default value of the method to make it easier to use. It is also a small trick. You can understand this usage. 650) this. width = 650; "src =" http://www.bkjia.com/uploads/allimg/131228/205K13W8-0.jpg "title =" Capture. JPG "/>

Then, when we call

650) this. width = 650; "src =" http://www.bkjia.com/uploads/allimg/131228/205K12Y1-1.jpg "title =" Capture. JPG "/>

That is, we do not need to enter this bool value. The default value is false. This true value is passed in only when this method parameter is required to be true. I just briefly demonstrated this default value, so you can understand it.
