如何在java中让Excel或记事本从浮点数字键盘输入数字

import java.util.Scanner;

Scanner scanner = new Scanner(System.in);
double number = scanner.nextDouble();

import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Sheet1");

Row row = sheet.createRow(0);
Cell cell = row.createCell(0);
cell.setCellValue(number);

FileOutputStream fileOut = new FileOutputStream("path/to/excel/file.xlsx");
workbook.write(fileOut);
fileOut.close();
workbook.close();

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;

BufferedWriter writer = new BufferedWriter(new FileWriter("path/to/text/file.txt"));
writer.write(String.valueOf(number));
writer.close();
