如何显示 JLabel 动态列表中的文本
原标题:How to display text coming from a dynamic List in JLabel

在“控制台”中,我们可以做这样的事情:

 for(int i = 0 ; i <list.size();i++){
    System.out.print("name :"+list.get(i).getName());
    System.out.print("  year :"+list.get(i).getYear());
    System.out.println();
 }

如果我们知道大小,我们可以 折叠许多标签和做到这一点

标签。 setText (” ) ;

如果我们不知道名单的大小,

最佳回答
System.out.print("name :"+list.get(i).getName());
System.out.print("  year :"+list.get(i).getYear());
System.out.println();

问题回答

您可以使用"http://docs.oracle.com/javase/tuative/uiswing/upports/html.html" rel=“nofollow”>HTML来格式化任何显示文本的 Swing 组件中的文本

StringBuilder b = new StringBuilder("<html>");
for(String s : list) {
    b.append(s);
    b.append("<br>");
}

label.setText(b.toString()); // multiline JLabel

标签.setText( label. getText () +“ + s”; 使用 < a href=" http://docs. oracle.com/javase/ 1. 5. 0/docs/ guide/ langues/ langues/foreach.html" rel=“ nofollow” {{{code> for- Each Loop。

例如:

for (String s : listOfStringType){
    label.setText(label.getText() + " " + s);
}
