在java中读取某个文件中的数据内容

代码

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.HashSet;
import java.util.Set;

public class ReadText {
          
   
	//读取文件中的所有内容
	public static void main(String[] args) {
          
   
		String path = "D:\face0713\fi1980630827.flsx";
		String s = toArrayByFileReader1(path);
		System.out.println(s);
	}

	
	public static String toArrayByFileReader1(String name) {
          
   
        // 使用ArrayList来存储每行读取到的字符串
        StringBuilder s = new StringBuilder();
        String txt = "";
        try {
          
   
            FileReader fr = new FileReader(name);
            BufferedReader bf = new BufferedReader(fr);
            String str;
            // 按行读取字符串
            while ((str = bf.readLine()) != null) {
          
   
                s.append(str);
            }
           txt = s.toString();
        } catch (IOException e) {
          
   
            e.printStackTrace();
        }
        return txt;
    }

}
