Answer 1

Actually in that line sumArray is an integer array and you are assigning it as integer only and also you haven't declared variable j. Try this-

public int[] arrayAdd(int[] R1, int[] R2)
{
    int[] sumArray= new int[R1.length];

    if( R1.length!= R2.length)
    {
        System.out.println("The arrays must be same length");
    }
    else
    {
        for(int i=0; i< R1.length; i++)

        {

            sumArray[i]= R1[i]+ R2[i]; // Error
        }
    }
    return sumArray;
}
