public class Sort{
public static void main(String[] args) throws IOException {
FileReader in = null;
FileWriter out = null;
BufferedReader read;
BufferedWriter write;
String temp[] = new String[100];
try {
in = new FileReader("A.txt");
out = new FileWriter("B.txt"); }
catch (FileNotFoundException e) { System.out.println("未找到文件");}
read = new BufferedReader(in);
write = new BufferedWriter(out);
String source;
int index = 0;
while((source = read.readLine()) != null){
temp[index] = source + "\n";
index++;
}
read.close();
for(int i=index-1; i>=0; i--){
write.write(temp[i]);
write.newLine();
write.flush();
}
write.close();
}
}
