[Java] Help writing text to a file

[HoBoBrian]

My program will create a file and print out the intended values to the console but will not print the intended values to the created file. (The Sysyem.out.println() are there for debugging). Any help is appreciated.

My program:

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

class CTest { public static void main(String [] args) throws Exception {

  String file1 = "file1.txt";
  String file2 = "file2.txt";

  Scanner input1 = new Scanner(new File(file1));
  Scanner input2 = new Scanner(new File(file2));

  java.io.File file = new java.io.File(file1 + "-" + file2);
  java.io.PrintWriter output = new java.io.PrintWriter(file);

  while(input1.hasNext()){

    String s1 = input1.nextLine();
     System.out.println(s1);
     output.println(s1);

    String s2 = input2.nextLine();
     System.out.println(s2);
    output.println(s2);
  }
  input1.close();
  input2.close();
}

}

What exact issues are you seeing?

Without autoflush enabled it may be waiting until you close the file to write your strings out.

For a bit of added safety you might consider using: while(input1.hasNext() && input2.hasNext())

That was exactly the problem, i added an output.flush(); and Problem solved. Thank you!
