如题，输入 1 2 3 4 5 6 7 8 9 0的时候，记事本里显示了这几个数是对的，但读取时就变了。。。

import *;
public class Idu{
    public static void main(String[] args ) throws IOException{
        DataOutputStream out = new DataOutputStream(new FileOutputStream("gb.txt"));
        int units;
        long p;
        for( int i = 0;i<10;i++){
            System.out.println("输入第"+(i+1)+"个数：");
            units = System.in.read();
            p = System.in.read();
            p = System.in.read();
            out.writeInt(units);   
        }
        out.close();
   
        DataInputStream in = new DataInputStream(new FileInputStream("gb.txt"));
        int unit;
        for( int i = 0;i<10;i++){
            unit = in.readInt();
            System.out.println(unit);
        }
        in.close();
    }
}

编码问题  读到内存里的时候 编码设置一下

    public static void main(String[] args) throws IOException {
        DataOutputStream out = new DataOutputStream(new FileOutputStream("gb.txt"));
        BufferedReader bis=new BufferedReader(new InputStreamReader(System.in));
        int units;
        for( int i = 0;i<10;i++){
            System.out.println("输入第"+(i+1)+"个数：");
            units = Integer.parseInt(bis.readLine());
            out.writeInt(units);   
        }
        out.close();
   
        DataInputStream in = new DataInputStream(new FileInputStream("gb.txt"));
        int unit;
        for( int i = 0;i<10;i++){
            unit = in.readInt();
            System.out.println(unit);
        }
        in.close();
    }
