title: How to use split method with stringbuilder together in the same class?
body: <p>StringBuilder to hide vowels:</p>
  
  <pre><code>String bienvenue_intro = " Welcome! Java First Semester: 455, java street: City (State): Country: 575757 ";
  StringBuilder sb = new StringBuilder(bienvenue_intro);
  String[] introduction = bienvenue_intro.split(":"); 
  for (int i = 0; i &lt; bienvenue_intro.length(); i++) {
      char c = bienvenue_intro.charAt(i);
      if ((c == 'A') || (c == 'a') ||
          (c == 'E') || (c == 'e') ||
          (c == 'I') || (c == 'i') ||
          (c == 'O') || (c == 'o') ||
          (c == 'U') || (c == 'u')) {
              sb.setCharAt(i, '*');
      }
  }
  System.out.println(bienvenue_intro);
  System.out.println(sb.toString());
  </code></pre>
  
  <p>The output of the above code is:</p>
  
  <pre><code>Welcome! Java First Semester: 455, java street: City (State): Country: 575757 
   W*lc*m*! J*v* F*rst S*m*st*r: 455, j*v* str**t: C*ty (St*t*): C**ntry: 575757 
  </code></pre>
  
  <p>Method split to break the lines:</p>
  
  <pre><code>for (int i = 0; i &lt; introduction.length; i++)
      System.out.println(introduction[i]);
  </code></pre>
  
  <p>The desired output using split + string builder would be:</p>
  
  <pre><code>W*lc*m*! J*v* F*rst S*m*st*r
  
   455, j*v* str**t
  
   C*ty (St*t*)
  
   C**ntry
  
   575757 
  </code></pre>
  
  <p>But both together it does not work! Is it even possible to team StringBuilder with the Split method?</p>
