我收到以下错误
java.io.FileNotFoundException: in.txt, (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileInputStream.<init>(Unknown Source)
at java.io.FileReader.<init>(Unknown Source)
at FileTest.main(FileTest.java:50)
但是我确定我在 src、bin 和根目录下创建了一个 in.txt 文件。我还尝试在主要参数中指定完整目录,但仍然无法正常工作。为什么 Eclipse 不选择它?
import java.io.*;
public class FileTest {
public static void main(String[] args) {
try {
String inFileName = args[0];
String outFileName = args[1];
BufferedReader ins = new BufferedReader(new FileReader(inFileName));
BufferedReader con = new BufferedReader(new InputStreamReader(System.in));
PrintWriter outs = new PrintWriter(new FileWriter(outFileName));
String first = ins.readLine(); // read from file
while (first != null) {
System.out.print("Type in a word to follow " + first + ":");
String second = con.readLine(); // read from console
// append and write
outs.println(first + ", " + second);
first = ins.readLine(); // read from file
}
ins.close();
outs.close();
} catch (IOException ex) {
ex.printStackTrace(System.err);
System.exit(1);
}
}
}
