我在线程“main”java.lang.Error 中遇到异常:未解析的编译:在 FileTest.main(FileTest.java:39) 第 39 行是public static void main(String[] args){
我做错了什么?
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);
}
}
}
}
