我失去了append方法。
我有一个程序可以输入信息，然后在文本文件中打印。
问题是，我也想将新的信息输入附加到文本文件中而不覆盖，这意味着如果我重新运行程序，我编码的信息将与程序最后一次运行时编码的信息一起出现在文本文件中。
请帮我。这是程序：
@SuppressWarnings("resource")
public static void main(String[] args) throws IOException
{
System.out.println("STUDENT INFORMATION");
System.out.println("-------------------");
System.out.println("Full Name : ");
Scanner sc = new Scanner(System.in);
String name = sc.nextLine();
System.out.println("\nCourse and Year : ");
String yearcourse = sc.nextLine();
System.out.println("\nStudent Number : ");
String studentnumber = sc.nextLine();
System.out.println("\nE-mail Address : ");
String eadd = sc.nextLine();
System.out.println("\nCellphone Number : ");
String cpnumber = sc.nextLine();
System.out.println("\nGender : ");
String gender = sc.nextLine();
System.out.println("\nAge : ");
String age = sc.nextLine();
System.out.println("\nDate of Birth : ");
String dob = sc.nextLine();
System.out.println("\nCivil Status : ");
String status = sc.nextLine();
System.out.println("\nAddress : ");
String address = sc.nextLine();
System.out.println("\n\n________________________________________________");
System.out.println("STUDENT INFORMATION");
System.out.println("\nName : " + name + "");
System.out.println("Year and Course : " + yearcourse + "");
System.out.println("Student Number : " + studentnumber + "");
System.out.println("E-mail Address : " + eadd + "");
System.out.println("Cellphone Number : " + cpnumber + "");
System.out.println("Gender : " + gender + "");
System.out.println("Age : " + age + "");
System.out.println("Date of Birth : " + dob + "");
System.out.println("Civil Status : " + status + "");
System.out.println("Address : " + address + "");
System.out.println("");
File file = new File("Student Information.txt");
if(!file.exists())
{
file.createNewFile();
}
try (PrintWriter writer = new PrintWriter(file)){
BufferedWriter bufferWritter = new BufferedWriter(writer);
writer.println("\nSTUDENT INFORMATION:");
writer.println("--------------------");
writer.println("Name : " + name + "");
writer.println("Year and Course : " + yearcourse + "");
writer.println("Student Number : " + studentnumber + "");
writer.println("E-mail Address : " + eadd + "");
writer.println("Cellphone Number : " + cpnumber + "");
writer.println("Gender : " + gender + "");
writer.println("Age : " + age + "");
writer.println("Date of Birth : " + dob + "");
writer.println("Civil Status : " + status + "");
writer.println("Address : " + address + "");
writer.flush();
}
}
}
在这。如果我重新运行程序，文本文件将被新的编码信息覆盖。他们说要使用 append bufferwriter。但我真的迷路了。
