Java将长行文本解析为多行
[英]Java parsing long lines of text into multiple lines
问题描述
I am new to programming and I would like some tips. 
我是编程新手，我想要一些技巧。 I have a program that reads from a text file using the the following method: 我有一个使用以下方法从文本文件读取的程序：
BufferedReader reader = new BufferedReader(new FileReader(file));
.....
This works but the problem is that some lines are long and I can't see all the text in the GUI. 这行得通，但问题是有些行很长，我无法在GUI中看到所有文本。 How should I tell Java to go to next line if length is equal to a certain amount? 如果长度等于一定量，我应该如何告诉Java下一行？
Example text: 示例文字：
A week after Mozart died, his ghost was discovered trying to erase his music. When asked why, it said "I'm decomposing.
Instead of two lines, I want to parse it into four lines. 我想将其解析为四行，而不是两行。 Any help would be appreciated. 任何帮助，将不胜感激。

as per your comments, you are using JLabel for displaying the data. 根据您的评论，您正在使用JLabel显示数据。
to show multi-line text in JLabel just wrap your text in <html> tag like: 要在JLabel中显示多行文本，只需将文本包装在<html>标记中，例如：
JLabel label = new JLabel("<html>your long text here ....</html>");
example: 例：
String theReadLineFromTextFile = ....;
theReadLineFromTextFile = "<html>"+theReadLineFromTextFile+"</html>";
JLabel label = new JLabel(theReadLineFromTextFile);
//or
JLabel label = new JLabel();
label.setText(theReadLineFromTextFile);

如果您无法在gui中执行此操作，则此处的一些答案将有所帮助： 在Java中，将多个字符按字面顺序包装在字符串后
