尝试运行以下tutorial中提到的代码 一切都完美编译,但它显示主方法中的错误。
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Stack;
import java.util.jar.Attributes;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import jdk.internal.org.xml.sax.SAXException;
import jdk.internal.org.xml.sax.helpers.DefaultHandler;
public class SaxParserExample {
public static void main (String argv []) {
SAXParserFactory factory = SAXParserFactory.newInstance();
try {
InputStream xmlInput =
new FileInputStream("data\\sax-example.xml");
SAXParser saxParser = factory.newSAXParser();
SaxHandler handler = new SaxHandler();
saxParser.parse(xmlInput, handler);
for(Driver driver : handler.drivers){
System.out.println(driver);
}
} catch (Throwable err) {
err.printStackTrace ();
}
}
}
在以下一行:
saxParser.parse(xmlInput, handler);
错误:
error: no suitable method found for parse(InputStream,SaxHandler)
saxParser.parse(xmlInput, handler);
method SAXParser.parse(InputStream,HandlerBase) is not applicable
(argument mismatch; SaxHandler cannot be converted to HandlerBase)

正如您所看到的,我已经包含了必要的文件但它没有编译。
答案 0 :(得分:1)
更改
的导入import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
到
set thePW to "MY_PASSWORD"
set thePane to "Security & Privacy"
activate application "System Preferences"
delay 1
tell application "System Events"
tell process "System Preferences"
click menu item thePane of menu "View" of menu bar 1
delay 3
if title of button 1 of window 1 is "Click the lock to make changes." then
click button 1 of window 1
delay 2
keystroke thePW
keystroke return
end if
end tell
end tell
