title: How do you subtract one array of chars from another in Java?
body: <p>Let's say I have an array, arrayA = ["a", "b", "c", "d", "e", "f"], 
  and another array, arrayB = ["a", "d", "e"]. </p>
  
  <p>I want to subtract arrayB from arrayA to yield the result = ["b", "c", "f"]</p>
  
  <p>This is my setup for each array:</p>
  
  <pre><code>char[] arrayA = new char[7];
  for(char c = 'a'; c &lt;= 'f'; ++c) {
      arrayA[c - 'a'] = c;
  }
  char[] arrayB = new char[]{'a','d','e'};
  </code></pre>
  
  <p>(Please excuse any improper use of symbols and syntax, I'm a Ruby noob trying to learn Java simply from the Oracle tutorials. Thanks!)
