public class PairOfElementsInArray {
   static void findThePairs(int inputArray[], int inputNumber)
   {
      System.out.println("Pairs of elements whose sum is "+inputNumber+" are : ");
      for (int i = 0; i < inputArray.length; i++)
      {
         for (int j = i+1; j < inputArray.length; j++)
         {
            if(inputArray[i]+inputArray[j] == inputNumber)
            {
               System.out.println(inputArray[i]+" + "+inputArray[j]+" = "+inputNumber);
            }
         }
      }
   }
   public static void main(String[] args)
   {
      findThePairs(new int[] {4, 6, 5, -10, 8, 5, 20}, 10);
      /*findThePairs(new int[] {4, -5, 9, 11, 25, 13, 12, 8}, 20);
        findThePairs(new int[] {12, 13, 40, 15, 8, 10, -15}, 25);
        findThePairs(new int[] {12, 23, 125, 41, -75, 38, 27, 11}, 50);*/
   }
}

Output:

Pairs of elements whose sum is 10 are :
4 + 6 = 10
5 + 5 = 10
-10 + 20 = 10
