一个关于swing实时翻译的java文件
首先是我的架构，分别是启动，百度api接口的调用文件，swing的界面设计文件
其中的依赖是酱紫的（自己敲）
<dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> <version>2.8.9</version> </dependency>
以下是代码，拿来能直接交

mian.java（启动!）
import translation.Api; import ui.Main; import java.util.ArrayList; public class mian { public static void main(String[] args) { Main main=new Main(); ArrayList<String> arrayList=new ArrayList<String>(); arrayList.add("中文"); arrayList.add("英文"); arrayList.add("日文"); arrayList.add("泰文"); arrayList.add("粤语"); main.display("",arrayList); } }
百度翻译的接口，具体名称好像叫通用文本翻译，对了泰语好像不行，然后。。。无
