从文本文件中读取字符串以插入输入(reading a string from text file to be inserted into input)

假设我有一个文件名“abc.txt”

这个文件有三个字符串“你好吗”

我想把字符串读作“你好吗”

并将其存储到字符串word2？

我该怎么做 ？

Lets say i has a file name "abc.txt"

This file has three strings " how are you "

I would like to read the strings as "how are you"

and store it into a string word2 ?

How can i do it ?

try { File file = new File("abc.txt"); BufferedReader br = new BufferedReader(new FileReader(file)); String word2 = br.readLine(); br.close(); //test: System.out.println(word2); } catch (IOException e) { // Something went wrong, eg: file not found e.printStackTrace(); } try { File file = new File("abc.txt"); BufferedReader br = new BufferedReader(new FileReader(file)); String word2 = br.readLine(); br.close(); //test: System.out.println(word2); } catch (IOException e) { // Something went wrong, eg: file not found e.printStackTrace(); }
