为什么Netbeans会覆盖我的代码？

Question

I am having a slight problem. I believe that my Netbeans is set to overwrite, so when ever I type something, it deletes whats in front of it. The editor cursor has also changed, from the usual vertical line, to a solid black block. Any Ideas?

Answer 1

Try pressing the Insert button on your keyboard. You can confirm this by looking the lower right hand corner a 'OVR' means you are in Overwrite mode, whereas 'INS' means you're in insert mode(the mode you want to be in).

See Wikipedia docs on Insert Key , also see highlighted button shown below:

Answer 2

按键盘上的插入键。
