java - 如何解决用户在java中使用BufferedReader输入时出现的错误 "Incompatible types"？

Question

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

    int x;
    InputStreamReader inputStreamReader = new InputStreamReader(System.in);
    BufferedReader bufferReader = new BufferedReader(inputStreamReader);
    x = bufferReader.readLine();
}

bufferReader.readLine() 返回String。 将 int x 更改为 String x

String x;
 ....
  your code
 ....
x = bufferReader.readLine();
Integer y= Integer.parseInt(x);
