pbl, you got it!

Thanks everyone for your response. I tried what pbl advised and it worked.

Let me be more specific:

I have text file like this:

america mexico canada
china india australia
brazil chile russia

I want to use thr random excess file to read up to the word india and store the words in an array. Then start reading from australia
up to the end and store in another array.

Here's my code:

raf.seek(0);  
    System.out.println("The second number is " + raf.readLine());
    StringTokenizer tokens;
	tokens = new StringTokenizer(line); 
	int i = 0; 
	long start = raf.length()/2;

	while (line != null && i < start) 
   {
     
	while(tokens.hasMoreTokens())
				System.out.println(tokens.nextToken());
    line = raf.readLine();
    tokens = new StringTokenizer(line); 
	i++;
   }

What i need help on is how to read up to the word india using seek method. I tried to find the entire length of the file and divided it by two so that I can read up the middle, but it seems not to be working

thanks man

I have gotten this far now:

 
    			  List list = load.getFile(); 
			
	                   int begin = 0; 
			
			for(int i = 1; i <= num; i++)
			 { 
			    end = (list.size()/num) *i;
				
			    process[i] = rt.exec("java subProcess"); 
			// get an ObjectOutputStream for sending data to the child 
	         OutputStream os = process[i].getOutputStream();
	         ObjectOutputStream obj = new ObjectOutputStream(os);
             obj.flush();  // outputs the bytes to another outputstream 
               System.out.println("Parent sending: " + list.subList(begin, end));
				// send the ArrayList to the child
	           objos.writeObject(list.subList(begin, end)); 
			   obj.flush();
              begin = end+1; 
			  
			}

I am however getting this error:



C:\JAVA>java MultiProcess
Enter the number of processes : 2

Parent sending: [child, mango, orange, zebra, theory, tomato]
java.io.NotSerializableException: java.util.RandomAccessSubList
at java.io.ObjectOutputStream.writeObject0(Unknown Source)
at java.io.ObjectOutputStream.writeObject(Unknown Source)
at MultiProcess.main(MultiProcess.java:49)

It doesnt allow me to sned the data to the child process. Why ?

Suppose I have amethod called getArray() that returns the arrayList of thousand string words.
Runtime runtime = Runtime.getRuntime();
// Create a child process
Process process = runtime.exec("java subProcess");

OutputStream output = process.getOutputStream();
ObjectOutputStream obj = new ObjectOutputStream(output);
obj.flush();

obj.writeObject(getArray()); // sending the array to the child process for further processing
objos.flush();

As you can see, I am only creating one process and sending the entire doc to it. I would like to create two processes, split the doc into half and send the first half to the first process and second half to the second process.
