JAVA - Read values in from text file

[jjbkeeper]

Howdy

Need some simple assistance with Java programming. Can't quite crack it.

I have a text file that has information as below

(1,7)(2,0)(4,0)(5,0)
(4,0)(2,0)(4,0)(5,0)
(1,1)(4,1)(1,25)(4,0)
(5,0)(4,0)(5,0)(6,1)
(5,0)(5,0)(5,0)(5,0)

I need to read in integer 1 and assign it to an integer (cmd) inside my program, and then read in integer 2 and assign it to another integer (data). It should then keep rotating through the text file until it comes to the end.

The code I currently have in this method is -

 public static load()
  {
   Scanner scanner = new Scanner(new File(memory.dat));
   int reg1 = 0;
   int reg2 = 0;
   int cmd = File(:, 1); //I stole this from MATLAB to read in from the file, but it didn't work, though I didn't think it would
   int data = File(:,2);
   
   if (cmd == 1)
    {
	 reg1 = data;
	}
   else
    if (cmd == 2)
	 {
	  reg1 = reg1 + 1;
	  if (reg1 > 26)
	   {
	    reg1 = 26;
	   }
	 }
    else
     if (cmd == 3)
      {
       reg1 = reg1 - 1;
	   if (reg1 < 0)
	    {
	     reg1 = 0;
		} 
      }
	 else
	  if (cmd == 4)
	   {
	    int temp = reg1;
		reg1 = reg2;
		reg2 = temp;
	   }
	  else
	   if (cmd == 5)
	    {
		 ascii = reg1 + 65;
		 System.out.println((char)ascii);
		} 
  }

If there has been a thread with this kind of assistance in it please direct me to it.

Thanks

The link below explains how to read from a file. String.split(" ") will help you get each pair of numbers out, and you'll want a loop around the main section of code if it's to be run for every pair of numbers.

Also, you'll probably find it easier to read the whole file to a variable then process it, rather than reading each number then process then read, then process etc.

And a helpful website, the Java API: http://java.sun.com/javase/6/docs/api/

Thanks for that. Helped a bit, but I'm still trying to figure out how to incorporate that in to my method. Can you assist by incorporating it into the method?
