1,将内容读取到map集合中:
public class Text02 {public static void main(String[] args) throws IOException {//创建缓冲输入流:BufferedReader bos = new BufferedReader(new FileReader("G:\\xxx\\student.txt"));//创建map集合HashMap<String, Integer> map = new HashMap<>();//将读取的行内容保存;String line;//循环读取while ((line = bos.readLine()) != null){String[] split = line.split("=");map.put(split[0],Integer.parseInt(split[1]));}//map遍历:map.forEach((s,value) -> {System.out.println(s+"::"+value);});}}
