[SOLVED] Making a program to open a file (.exe)

[linux1man]

Ok i have been trying to create a java program that would open an executable file when entered a password. (I am making the java program an executable using exe4j)
This is my code so far: (it does not work because you can't do: file.open())

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

public class Passcode
{
public static void main (String[]args)
{
Scanner keyB = new Scanner (System.in);

String ans = "password";
String pass;

System.out.println("Enter a password: ");
pass = keyB.nextLine();

if (pass.equals(ans))
{
File file = new File("C:/Program Files/WarCraft3/WC3.EXE");
file.open();

}
else
System.out.println("Invalid Password");

}
}

Does anybody have any suggestions?
Please reply.

Hi Linux,

Hope this helps:

The easiest way for you to run exe at run time (i.e., you'll have to make
sure that it exists) is to use the Java's built-in Process.

The general way is
Process process = Runtime.getRuntime().exec(as, es, dir);

where as is the String [] of the command (full-path) and its arguments,
es is the String [] of the environments (more suitable in unix)
dir is a File specifying the working directory.

Thus, if the file is MyExe.exe that resides in c:\mydir, you'll do
as[0] = "c:\mydir\MyExe.exe";
es = null;
dir=new File("c:\mydir");
.... exec(as,es,dir);

as[0] = "c:\Program Files\WarCraft3\WC3.EXE";
es = null;
dir=new File("c:\Program Files\WarCraft3\");


Also, remember to use "\" instead of "/" for directory's ;)

Or else, at least search on the forum. There are thousand of answers related to your question.

Thanks for all the help!:D

so what was the final code that works?

and were do you find "Runtime Class doc" so you can read it?
I did a forum search but wasted my time

I notice you might have to go
File file = new File("C:\\Program Files\\WarCraft3\\WC3.EXE");

[linux1man]

For some reason I can not post links, but just google runtime class java, it should be the first thing to come up.

So what does the code look like? that will get closer to your "post count must be 20 or greater"

here's the code: 9here i use the program to open audacity with password

import java.util.Scanner;
import java.io.File;

public class open
{
public static void main (String[]args) throws Exception
{
Scanner keyB = new Scanner (System.in);
String ans = "hacker";
String trying;

System.out.println("****************************** **********");
System.out.println("* Anti-deleter *");
System.out.println("* By:**************** *");
System.out.println("****************************** **********");

System.out.print("\nPlease enter a password: ");
trying = keyB.nextLine();

if (trying.equals(ans))
{
System.out.println("Correct password!");
Process p = Runtime.getRuntime().exec("C:/Program Files/Audacity/audacity.EXE");
}

else
System.out.println("Invalid password!");
}
}
