本文提供了一个Java程序示例，演示如何从控制台读取用户输入的字符串，并将其输出到屏幕和写入到文件中。此外，还展示了如何使用FileOutputStream将字节数组写入文件。

import java.io.BufferedReader;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;

class HasStatic {
   private static int x = 100;

    public static void main(String[] args) {

            /*FileInputStream fis;
            FileOutputStream out;
            try {
                fis = new FileInputStream("d:/text.txt");
                BufferedInputStream bs=new BufferedInputStream(fis);
                out = new FileOutputStream("d:/new.txt");
                byte[] b=new byte[512];
                int len;
                while((len=bs.read(b,0,512))!=-1){
                    out.write(b,0,len);
                    out.flush();
                }
                fis.close();
                out.close();
            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            */
        try {
            BufferedReader br=new BufferedReader(new InputStreamReader(System.in ));
            String s=br.readLine();
            System.out.println(s);
            FileOutputStream out=new FileOutputStream("d:/tt.txt");
            byte[] b=s.getBytes();
            out.write(b);
            out.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    }
}
