我有这个java代码，我想返回2个值，然后在main()或其他函数中使用它们。请提供一些帮助。发送:
import java.net.*;
import java.io.*;
import java.io.File;
import org.apache.commons.io.FileUtils;
import org.apache.commons.lang.StringUtils;
public class URLReader {
public String[] functie(String x) throws Exception
{
URL oracle = new URL(x);
BufferedReader in = new BufferedReader(new InputStreamReader(oracle.openStream()));
String inputLine=null;
StringBuffer theText = new StringBuffer();
while ((inputLine = in.readLine()) != null)
theText.append(inputLine+"\n");
String html = theText.toString();
in.close();
String[] tds = StringUtils.substringsBetween(html, "<tr>", "</tr>");
String[] tds2 = StringUtils.substringsBetween(tds[1], "href=\"/module/gallery", "\"><img");
String[] tds3 = StringUtils.substringsBetween(tds[1], "src='/redx_tools/mb_image.php", "' border='1'");
return ???
}
public static void main(String[] args) throws Exception {
String x = new String("http://www.wippro.at/module/gallery/index.php?limitstart=0&picno=0&gallery_key=59");
URLReader s = new URLReader();
for (String st : s.functie(x))
{
System.out.println(st);
}
}
}
最佳答案
你的琴弦是自己制作的吗？如果a和b是你想要返回的String对象，你可以构建一个String数组来返回，如下所示:
return new String[] {a, b};
您已在代码中构建了三个字符串数组:tds、tds2 和 tds3。所有这些都可以在一个大数组中返回，如下所示:
String[] retArray = new String[tds.length+tds2.length+tds3.length];
System.arrayCopy(tds, 0, retArray, 0, tds.length);
System.arrayCopy(tds2, 0, retArray, tds.length, tds2.length);
System.arrayCopy(tds3, 0, retArray, tds.length+tds2.length, tds3.length);
return retArray
