How to convert a string into the sum of ASCII values? in java, OOP

asciiValue.java

public class main {
  public static void main(String[] args) {
	Ascii a = new Ascii();  //make an object
	a.setS("An example");   // the string we want to get the sum of it in asii
	a.asciValue(a.getS());  // pass the string as argument 
	a.print();              // print the result
 }
}

class Ascii{
  private String s;
  int result =0;
	
  // encapsulation 
  public void setS(String val) {
	this.s = val;
  }
  
  public String getS() {
	return s;
	}
	
  // method to calc. the sum of string in ascii
  public int asciValue(String a) {
    
	char[] c = a.toCharArray();  // convert the string to array of chars
		
	for (char i: c) {
		result+= (int) i;         // convert each char to it's value in ascii
	}
	eturn result;
  }
	
  // method to print the result
  // you can get rid of it 
  public void print() {
	System.out.println(result);
  }
}
