class Sum

{ private int sum;

public int getSum()

{ return sum;

}

public void setSum(int sum)

{ this.sum=sum;

}

}

class Summation implements Runnable

{ private int upper;

private Sum sumValue;

public Summation(int upper, Sum sumValue)

{ this.upper=upper;

this.sumValue=sumValue;

}

public void run()

{ int sum=0;

for(int i=0; i<=upper;i++)

sum+=i;

sumValue.setSum(sum);

}

}

public class TestJavaThread

{ public static void main(String[] args)

{

int upper = 10;

/* create the object which will be shared by the thread */

Sum sumObject=new Sum();

/* create a thread object */

Thread thrd=new Thread(new Summation(upper,sumObject));

/* Create and use thread */

thrd.start();

try

{ thrd.join();

System.out.println("the sum from 1 to " + upper +" is " +sumObject.getSum());

} catch (InterruptedException ie) {}

}
