此论坛的新手和Java新手。我试图从文本字段中搜索数组列表。这是一个例子：用户将在文本字段中键入部分描述，按回车键，它将在数组列表中搜索描述，并在JOptionPane中打印信息。我想我最终希望将它打印在带有滚动条的文本区域中，因为可能有多行。示例：用户类型拟合，它将搜索数组列表，然后打印出来＆＃34;描述:(拟合，带刺，旋转弯头）位置：c04-01-e04 PB部件号：34036制造商＃：208302＆＃34;。搜索拟合实际上会打印许多行。我将发送2个程序，每个程序在不同的帖子中。第一个将是我试图去上班的人。我知道的第二个工作，但只打印到控制台。我希望这是有道理的。

尝试更换

if(Run.partsList.get(i).getDesc().contains(desc.toLowerCase())){
JOptionPane.showMessageDialog(null, "HELLO");
return;
}
}
带
for (String des : Run.partsList) {
