    Default Why my void run method cannot be execute?

    public class MyRun implements Runnable{
     
    	int[] array = new int[5];
    	int index;		
     
    	MyRun(int value, int index){
    		this.index = index;
    		array[index] = value;			
    		}
    	}
     
    	//run() method to do operation	
    	public void run(){
    		System.out.println("run()");
    		for(int count = 0; count < 5; count++)
    		System.out.println(array[count]);
    	}
    }
    and the main thread:
    import java.util.concurrent.*;
    public class satu {
    	public static void main(String[]args){

    		int lowest = array[0], highest = array[0];
    		int pivot;		
     
    		ExecutorService executor = Executors.newFixedThreadPool(1);		
     
    		for(int index = 1; index < array.length; index++){
    			//mission: find highest n lowest
    			if(lowest > array[index])
    				lowest = array[index];
    			else if (highest < array[index])
    				highest = array[index];
    		}		
     
    		pivot = array[lowest + (highest - lowest)/2];					
     
    		for(int count = 0; count < array.length; count++){
    			Runnable task = new MyRun(array[count],count);			
    		}

    You should submit the Runnable object to the ExecutorService, for example:

    executor.submit(task)
