如何读取文本文件并将其在netbeans JTextArea中显示？

Question

I'm working in a Netbeans GUI project. All I want to do is to read a text file from a path and display it in a JTextArea using Netbeans. How can I achieve this?

Is there any simple way to do this just using the file path?

Lets say i want this be done after a button click..

Answer 1

• read Oracles tutorial about How to Use Text Areas

• use JTextArea.read(Reader in, Object desc) throws IOException

Answer 2

请参阅JTextComponent.read(Reader,Object)以获取几乎一个“单行解决方案”。
