if you have an arrayList of tempArr = [hi, my, name, is, john] and another arrayList of tempArray2 = [a, b, c, d, e] and you want it to result in newArr = [hi a, my b, name c, is d, john e] how do you go about that?

public class CombineArrays {
 public static void combineValues(int length, int[] array1, int[] array2){      
        int col = 2;
        int k = 1;
        int[][] array = new int[length][col];   


        for( int i = 0; i < length; i++ )
        {
            for( int j = 0; j < 1; j++ )
            {
                array[i][j] = array1[i];
            }
            array[i][k] = array2[i];
        }

        print( array );
            }

public static void print(int[][]array){
    for (int i=0 ; i < array.length ; i++)
        {     System.out.println();
            for  (int j=0 ; j < array[i].length ; j++){
                System.out.print(array[i][j]+" ");
                  }
        }
}
    public static void main(String[] args)
     {
      int arr1[] = {7,7,3};
      int arr2[] = {4,6,2};
      combineValues(3,arr1,arr2);
     }
    }
