TargetValuesOfSum

 

//Find out the values which have sum = 10 from {1,3,5,6,2,4,9},  Ans = 6,4 and 1,9. This is an example only. Let's see the code below for such problems.

package abc;

import java.util.ArrayList;

import java.util.Arrays;

public class FindTargetValuesOfSum {

       public static void main(String[] args) { 

             int[] num = {1,3,5,6,2,4,9,7,8};

             int lengthArray = num.length;

             ArrayList<Integer> alist = new ArrayList<>();//To display output, but this does not work in this case as shown in the output

             int[] array = new int[2];//To display output

             for(int i=0;i<lengthArray;i++) {

                    for(int j=0;j<lengthArray;j++) {

                           if(num[i]+num[j] ==10) {

                                 System.out.println("Simple output for the sum of 10 can be achieved with : "+num[i]+" , "+num[j]);

                                 array[0]=num[i];

                                 array[1]=num[j];

                                 System.out.println("The output in Array = "+Arrays.toString(array));

                                 alist.add(num[i]);

                                 alist.add(num[j]);

                                 System.out.println("The output in ArrayList = "+alist);//This is not suitable in this case as shown in the result. So, discard the results from this sysout statement. I have kept the result here just to show you what will happen if you use arraylist the way it has been used here.

 

                           }

                    }

             }

 

       }
