Answer 1

Answer:

public static int sumStrings(String s1, String s2, String s3) {

       int i1 = Integer.parseInt(s1);

       int i2 = Integer.parseInt(s2);

       int i3 = Integer.parseInt(s3);

       

       int sum = i1 + i2 + i3;

       return sum;

   }

Explanation:

- Create a method called sumStrings that takes three strings

- Convert each string to integer using Integer.parseInt() method

- Sum the strings

- Return the result
