title: Using a dot in a string name
body: <p>The following line of code will not compile:</p>
  
  <pre><code>String 89.9 = new String("Hot 89.9");
  </code></pre>
  
  <p>It gives the following errors:</p>
  
  <pre><code>src/mainPackage/Userinterface.java:73: error: ';' expected
          String Hot89.9 = new String("Hot 89.9");
                      ^
  
  src/mainPackage/Userinterface.java:73: error: invalid method declaration; return type required
          String Hot89.9 = new String("Hot 89.9");
                               ^
  
  src/mainPackage/Userinterface.java:73: error: illegal start of type
          String Hot89.9 = new String("Hot 89.9");
  </code></pre>
  
  <p>Am I doing something wrong when I am creating my string?</p>
