title: call to super in a constructor implicitly or explicitly if commented or not. has same effect
body: <pre class="lang-java prettyprint-override"><code>class Person { 
      Person() { 
          System.out.println(&quot;This is person class&quot;); 
      } 
  } 
  
  class Student extends Person {
      Student() {
          super();
          System.out.println(&quot;This is student class&quot;);
      }
  }
      
  class Test { 
      Student s = new Student();
  }
  </code></pre>
  <p>The output is</p>
  <blockquote>
  <p>This is person class<br />
  This is student class</p>
  </blockquote>
  <p>But if I comment super() call in child class constructor, output is coming same, is it like, giving super() in child class is explicit call to a constructor?</p>
