Java编程实现向文本文件中读取数据之Scanner用法示例

package com.li;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.util.*;
public class Main {
  public static void main(String[] args) {
    // TODO 自动生成的方法存根
    Scanner inputStream = null;
    try
    {
      inputStream = new Scanner(new
         FileInputStream("stuff.txt"));
    }catch(FileNotFoundException e)
    {
      System.out.println("File stuff.txt was no
                     found");
      System.exit(0);
    }
    String line = inputStream.nextLine();
    System.out.println(line);
    inputStream.close();
  }
}
