IOException系统找不到路径怎么解决？

package mmm;

import java.io.DataInputStream;

import java.io.DataOutputStream;

import java.io.File;

import java.io.FileFilter;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.IOException;

import java.util.Scanner;

public class Stu2020110619001 {

   public static void main(String[] args) throws IOException{

    File file1=new File("E:/110619.txt");

    file1.createNewFile();

    System.out.println("请输入想要保存的内容（以%结尾）:");

    Scanner scanner =new Scanner(System.in);

    String string =scanner.next();

    DataOutputStream dataO = new DataOutputStream(new FileOutputStream("E:/110619.txt"));

    dataO.writeBytes(string);

    DataInputStream datal =new DataInputStream(new FileInputStream("E:/110619.txt"));

    String string2=datal.readLine();

    System.out.println("读取的字符为："+string2);

    System.out.println("110619");

   }

}

IO流读取数据异常，建议你看看原路径是否存在，以及数据格式是否正确
