问题描述
在JLabel的setText()方法中，我的String遇到了一些意外的问题.
I've encountered some unexpected problem with my String in the setText() method of JLabel.
无论我做什么，断言变量时都无法设置新行.
No matter what I do, it just can't get it to set a new line when asserting variables.
到目前为止我已经尝试过的
what i've tried so far
Jabel l = new JLabel();
String string = new String();
string = var1+"\n"+var2;
string = var1+"\r\n"+var2;
string = var1+"<html><br/></html>"+var2;
l.setText(string);
推荐答案
You can use HTML within the JLabel as described in the online tutorial, and you almost got it right; the text you want to wrap has to be enclosed within the HTML tags like:
string = "<html>" + var1 + "<br/>" + var2 + "</html>";
尽管最好使用StringBuilder实际构建字符串.
although it might be better to use StringBuilder to actually build the string.
