title: Object Parameters in a Constructor
body: <p>first of all I apologize if my question is difficult to understand. I'm having a hard time trying to explain exactly what I need help with. I am new to Java and the concept of passing by reference etc. </p>
  
  <p>Basically, I need to know why the below code is incorrect. How do I tell Java to use a method for an object passed in as a parameter of the constructor? Apologies again, and thanks for reading!</p>
  
  <pre><code>public ClassOne(ClassTwo twoObject){
  
  }
  
  public boolean OneMethod(){
      twoObject.MethodName(); // twoObject cannot be resolved.
  }
  </code></pre>
