请问在jbuilder 中, abc.txt 放在哪里，才能被程序找到呢？

package ab.cd.ef;
import java.io.*;

public class Untitled2 {
public Untitled2() {
}

public static void main(String[] args) {

FileInputStream fis = null;
try {
fis = new FileInputStream ("abc.txt");
System.out.println("Open Files Success ");
} catch (FileNotFoundException e) {
System.out.println("e.getMessage() = "+e.getMessage());
e.printStackTrace();
}

}
}
这是jbuilder 的运行命令

D:\JBuilder9\jdk1.4\bin\javaw -classpath
"F:\wanggq\Success\classes;
D:\JBuilder9\jdk1.4\demo\jfc\Java2D\Java2Demo.jar;

正确！


/* etSystemProperties.java */
import java.util.Properties;

public class GetSystemProperties {
  public static void main(String args[]) {
    Properties prop = new Properties(System.getProperties());
    prop.list(System.out);
  }
}

Posted by: pengtaoli Posted on: 2004-04-22 10:15 程序运行的目录应该没问题。我想放在path里应该可以找到
