Replacing all non letters with symbol * in string

My program only replaces the last non letter in string. Could someone help me:)?

Code:

---

Write a Java method to replace all non-letters in a given string s by symbol '*'.
public static String asenda (String s)

---

Code:

---

package soned;


public class soneExample3 {

  /**
    * @param args
    */
  public static void main(String[] args) {
  System.out.println(asenda(new String("H'o.m-m i_k")));
  }

  public static String asenda(String s) {
      String result ="";
     
      for(int i=0;i<s.length();i++) {
        if(!Character.isLetter(s.charAt(i))) {
          result = s.replace(s.charAt(i), '*');
        }
      }
     
      return result; 
  }
}

You're halfway there: you have to iterate over all characters in the String; if the current character is a letter you simply append it to the result; if it isn't a letter you append a '*' character to the result instead. Something like this:

Code:

---

char current= s.charAt(i);
if (Character.isLetter(current)) result+= current;
else result+= '*';

---

The code snippet above should be embedded in the for-loop body of your code.

kind regards,

ps. I removed your duplicate thread.

Thank You :)
