How to save the time to a .txt file and retrive it back as time?

Question

I have to save the time [hour:minute:second] and the date [date:month:year] to a .txt file. I am using the Calendar API to set the time and date as below
FileOutputStream fileStream = new FileOutputStream ("what.txt");
PrintWriter pw=new PrintWriter(fileStream, true);
Calendar curDate = Calendar.getInstance();
System.out.print(curDate.get(Calendar.DATE)+":");
System.out.print(months[curDate.get(Calendar.MONTH)]+":");
System.out.print(curDate.get(Calendar.YEAR));
pw.println(curDate);
I'll have to retrive these data back to use it to set timer
timer = new Timer();
timer.schedule(new RemindTask(), time);
I try to retrive the data and use the Calendar API to that data by using the below program.
I get the error as :
C:\t\Retrivedate.java:41: int cannot be dereferenced
System.out.print(t.get(Calendar.DATE)+":");
How can I solve this so that I can use Calendar API on my retrived data?
import java.io.*;
import java.util.*;
import java.lang.*;
class Test {
public static void main(String args[]) {
try {
File inputFile = new File("what.txt");
FileReader in = new FileReader("what.txt");
int t;
char[] tmp = new char[100];
int cnt = in.read(tmp);
String tm="";
for (int j=0;j<cnt;j++)
{ tm+=tmp[j];
try {
t=Integer.parseInt(tm,10);
catch (NumberFormatException exception) {}
System.out.println("jika "+tm);
Calendar curDate = Calendar.getInstance();
String months[]={
"Jan","Feb","Mar","Apr",
"May","June","July","Aug",
"Sept","Oct","Nov","Dec"};
Date time1 = curDate.getTime();
System.out.print(" \n"+time1.getHours());
System.out.print(":"+time1.getMinutes());
System.out.println(":"+time1.getSeconds());
System.out.print(t.get(Calendar.DATE)+":");
System.out.print(months[t.get(Calendar.MONTH)]+":");
System.out.print(t.get(Calendar.YEAR));
in.close(); }
catch (IOException ex) {
System.out.println("IOException:"+ex.toString()); }

Answer 1

These lines do not make sense:
System.out.print(t.get(Calendar.DATE)+":");
System.out.print(months[t.get(Calendar.MONTH)]+":");
System.out.print(t.get(Calendar.YEAR));
1. t is an integer, it does not have any methods.
2. It's a bad idea to use char[] to retrive the date. You should use readLine() method to retrieve the whole date string, say "10/23/2001" (certainly you can have hours, minutes, seconds, etc.). Then you need to use SimpleDateFormat class to parse this string. SimpleDateFormat gives you everything to parse a date string in any format you want.
