Thread: Simple computer login problem

so the problem with my code is it will not run unless i manually make a text file, i want it to check if the text files exist and if they do not (and they wont) then to create them, but i always come up with an error.
this is my source code, feel free to use it for yourself,(post fixed versions of my code please)

package computer.login.v2;

import java.io.*;
import java.util.*;

public class ComputerLoginV2 {

public static void main(String[] args) throws FileNotFoundException, IOException {


File user = new File("user.txt");
File pass = new File("pass.txt");

Scanner checksomep = new Scanner(pass);
int trys;
String loginstatus, username, password, firsttimeuser, firsttimepass1, firsttimepass2, usertry, passtry, reset;

loginstatus = "blocked";
trys = 0;
while (loginstatus.equals("blocked")) { //this is suppposed to create the new file
if (!user.getAbsoluteFile().exists()) {
user.createNewFile();
FileOutputStream userstream = new FileOutputStream(user);
}
if (!user.getAbsoluteFile().exists()){
pass.createNewFile();
FileOutputStream passstream = new FileOutputStream(pass);
}
loginstatus = "false";
} //end of problem

while (loginstatus.equals("false")) { //here on works

checksomeu.close();
checksomep.close();
checksomeu = new Scanner(user);
checksomep = new Scanner(pass);


if (!checksomeu.hasNextLine() || !checksomep.hasNextLine()) { //no login already set up
System.out.println("First Time Users"
+ "\nPlease enter a user name(write this down as you will need it later):");
firsttimeuser = getsome.nextLine();

System.out.println("And a password:");
firsttimepass1 = getsome.nextLine();

System.out.println("Enter the password again");
firsttimepass2 = getsome.nextLine();

if (firsttimepass1.equals(firsttimepass2)) {

password = firsttimepass1;
PrintStream console = System.out; //console defined normal output

FileOutputStream userstream = new FileOutputStream(user); //sends all file output to txt
PrintStream userprintstream = new PrintStream(userstream); //carlton print stream defined as a text file
System.setOut(userprintstream); //redefines stestem.our as to where is goes
System.out.println(username); //now text goes to the file

System.setOut(console); //switches back to the console
System.out.println("Your username has been set");//now its normal

FileOutputStream passstream = new FileOutputStream(pass); //sends all file output to txt

} else {

}

}
if (reset.equals("n")) {

}
}
if (loginstatus.equals("lockout")) {
System.out.println("Go hack someone elses basic java program!");
}
}
}

the error is run:

Please wrap your code in the code tags, and please post any and all errors

i want it to check if the text files exist

See the API for the File class, it contains a methods exists() to check if a File exists as well as to create a new File.

This is the new code with the .exists() and it comes up with this error:

Exception in thread "main" java.io.FileNotFoundException: user.txt (The system cannot find the file specified)
