import
java.io.*;
public class Ping {
public static void main(String[] args) {
String command="pig www.sohu.com
";
StringWriter sw = new StringWriter();
try {
Process
child=Runtime.getRuntime().exec(command);
child.waitFor();
System.out.println(child.exitValue());
} catch (
InterruptedException ie ) {
System.out.println( ie );
ie.printStackTrace(new PrintWriter(sw));
} catch
(IOException ioe) {
System.out.println(
ioe );
ioe.printStackTrace(new
PrintWriter(sw));
}
System.out.println(sw);
}
}
sw.toString()就是你要的String
e.printStackTrace是定向到err的输出中,如果要e的信息直接e.toString就可以了
如果用e.toString,信息不全面,不能知道错误的具体行数。
StringWriter sw=new
StringWriter();
………
………
e.printStackTrace(new
PrintWriter(sw,true));
String str=sw.toString;
//str中就是详细的错误信息。
