055 - Accumulator Method String Practice 3

Write a method header on line two with the following specs:

Returns: a String Name: censorLetter Parameters: a String called s a char called ch

 

Then complete the method by programming the following behavior

Replace all instances of ch with a "*" within the String s. See below examples.

 

Examples:

• censorLetter("computer science",'e') ==> "comput*r sci*nc*"
• censorLetter("trick or treat",'t') ==> "*rick or *rea*"

---

Solution

 

class Main {
    public static String censorLetter(String s,char ch)
    {        
        return s.replaceAll(String.valueOf(ch), "*");
    }
    
    //test case below (dont change):
    public static void main(String[] args){
        System.out.println(censorLetter("computer science",'e')); //"comput*r sci*nc*"
        System.out.println(censorLetter("trick or treat",'t')); //"*rick or *rea*"
    }
}
