title: Java: Pattern.compile()
body: <p>Consider following piece of code  </p>
  
  <pre><code>for(int i=0;i&lt;10;i++)  
    Pattern p=Pattern.compile(someExpression);     
  </code></pre>
  
  <p>Will this java code cause same pattern to compile 10 times or will it compile only once when i=0?</p>
