需要帮助从Java中的DataInputStream获取输入

Question

这是我的代码：

import java.io.*;

class InterestCalcs {

    public static void main(String arg[]) {
        Float prinAmount = new Float(0);
        Float ROI = new Float(0);
        DataInputStream in = new DataInputStream(System.in);
        String tempString;
        int noOfYears;
        System.out.println("Enter Amount :");
        System.out.flush();
        tempString = in .readLine();
        prinAmount = Float.valueOf(tempString);
        System.out.println("Enter ROI:");
        System.out.flush();
        tempString = in .readLine();
        ROI = Float.valueOf(tempString);
        System.out.flush();
        tempString = in .readLine();
        noOfYears = Integer.parseInt(tempString);
        float interestTotal = ROIprinAmountnoOfYears;
        System.out.println("The total interest is " + interestTotal);
    }
}

尝试使用BufferedReader

BufferedReader阅读器=new BufferedReader（new InputStreamReader（System.in））;

tempString = reader.readLine（）;
