    public class Sort {      public static void main(String[] args) {      
                int[] array = {3, 4, 12, 6, 7, 2, 3, 23, 1, 0, -9};             
         int i;                                               
    for (i=0;i<array.length;++i) {           
      System.out.print(" " + array[i]);                      }             
        System.out.println("");        
      int[] result = new int[array.length];     
    
         
    // what i have to do here                
    
      for (i=0;i<result.length;++i) {

    Hmm...
    Posting in the wrong forum - tick. (This is Java? code I think, certainly not C!)
    Bad spelling - tick.
    Bad punctuation - tick.
    Complete and utter lack of capitalisation - tick.
    Horrible code formatting - tick.
    Trying to solve a ridiculous problem - tick. (It would probably take more time to start a second thread than to just sort 11 numbers in one thread)

    Am I going to just move right along and ignore this thread? - one big fat tick!

    How i write Java application that sorts an array of integers using two threads. The rst thread
    sorts the rst half of the array, the second the second half. Both threads should run in parallel.
    After the threads have nished their work, the two halves must be merged into one sorted
    array.

    Code:
    public class Sort {     
     public static void main(String[] args) {      
         int[] array = {3, 4, 12, 6, 7, 2, 3, 23, 1, 0, -9};             
         int i;                                               
    for (i=0;i<array.length;++i) {           
      System.out.print(" " + array[i]);   
        }             
        
    System.out.println("");        
      int[] result = new int[array.length];     
     
          
    // what i have to do here                
     
      for (i=0;i<result.length;++i) {          
       System.out.print(" " + result[i]);             
             }               
    
       System.out.println("");      }
    
     }

    Are you deaf???? This is the C Forum, nobody cares about your Java rubbish
    1. Get rid of gets(). Never ever ever use it again. Replace it with fgets() and use that instead.
    2. Get rid of void main and replace it with int main(void) and return 0 at the end of the function.
    3. Get rid of conio.h and other antiquated DOS crap headers.
    4. Don't cast the return value of malloc, even if you always always always make sure that stdlib.h is included.

    The whole basis of this thread is dumb. Why would you need threads to sort an array of integers? Even in a suitably sized array, the work needed to start/stop/communicate between the threads, would be more than using only one.

    10 integers is all about "proof of concept". No doubt if the OP had posted something like 10M records, some people would be arguing to post a simplified problem (no win situation).
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
