java - 如何写入输出文件？

Question

如何将底部部分写入输出文件？它编译并运行，但关闭而不是将其写入文件。

我正确导入了所有内容。但我的输出文件不会打印到 TEACHERNAME.out？

import javax.swing.JOptionPane;
import java.io.FileReader;
import java.io.PrintWriter;
import java.util.Scanner;
import java.io.FileNotFoundException;
import java.util.Date;
public class Corpus03
{
  public static void main(String arg[])
   throws FileNotFoundException
   {

   Scanner inputFile = new Scanner(new FileReader("input.txt"));
   PrintWriter outFile = new PrintWriter("TEACHERNAME.out"); 

       //INPUT
   name = JOptionPane.showInputDialog("Enter your name: ");
   ID = JOptionPane.showInputDialog("Enter your ID: ");
   str = JOptionPane.showInputDialog("Enter your Annual Salary");
   annualSalary = Double.parseDouble(str);
   //CALCULATIONS
   grossPayPerCheck = annualSalary / 24;
   actualDayWorked = annualSalary / 174;
   perWeek = (annualSalary / 50);
   perHour = perWeek / 40; 
   ssTax = grossPayPerCheck * SS_TAX;
   medTax = grossPayPerCheck * MED_TAX;
   fedTax = grossPayPerCheck * FED_TAX;
   stateTax = grossPayPerCheck * STATE_TAX;
   unitedWay = 20;
   healthIns = 125;
   totalDeductions = ssTax + medTax + fedTax + stateTax + healthIns +    unitedWay;
   netPay = (grossPayPerCheck - totalDeductions);
   Date now = new Date();
   //OUTPUT
   outputStr = "Name: " + name
      + "\r\n" + "Employee ID: " + ID
      + "\r\n" + "Annual Salary: " + String.format("%.2f", annualSalary)
      + "\r\n" + "Gross Pay per Check: $"
      + String.format("%.2f", grossPayPerCheck)
      + "\r\n" + "$" + String.format("%.2f", actualDayWorked) + " per actual day worked"
      + "\r\n" + "$" + String.format("%.2f", perHour) + " per hour"
      + "\r\n\r\n" + "===================="
      + "\r\n" + "DEDUCTIONS PER CHECK"
      + "\r\n" + "===================="
      + "\r\n" + "Social Security Tax: $" 
      + String.format("%.2f", ssTax)
      + "\r\n" + "Medicare Tax: $"
      + String.format("%.2f", medTax)
      + "\r\n" + "Federal Income: $"
      + String.format("%.2f", fedTax)
      + "\r\n" + "State Income Tax: $"
      + String.format("%.2f", stateTax)
      + "\r\n" + "Health Insurance: $125.00"
      + "\r\n" + "United Way Contribution: $20.00"
      + "\r\n\r\n" + "Total Deductions: $" 
      + String.format("%.2f", totalDeductions)
      + "\r\n\r\n" + "Net Pay per check: $" 
      + String.format("%.2f", netPay);
   JOptionPane.showMessageDialog(null, outputStr, 
                     "Teacher Pay Information", 
                   JOptionPane.INFORMATION_MESSAGE);
   outFile.printf("City School Dstric, 111 First Stree, Anytown, OK 12345");
   outFile.println();
   outFile.println();
   outFile.printf("%-40s%-10s\r\n\n", name, ID);
   outFile.close();  
   inputFile.close();
   System.exit(0);
   }
}

我的代码唯一不做的就是写入单独的文本文件。 (是的，我还有更多需要写入文本文件，我只是给出了我需要的一些东西的示例。)

您可以将 PrintWriter 的相对路径指定为

PrintWriter outFile = 
            new PrintWriter("C:\\Users\\example\\IdeaProjects\\untitled\\news\\TEACHERNAME.out");

不要忘记将 \ 转义为 \\。现在您可以在绝对路径中看到TEACHERNAME.out。
