CallSuperInConstructor


CallSuperInConstructor
It is a good practice to call super() in a constructor. If super() is not called but
 another constructor (such as an overloaded constructor) is called, this rule will not report it.
      
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
        
//ClassOrInterfaceDeclaration[ count (ExtendsList/*) &gt; 0 ]
/ClassOrInterfaceBody
 /ClassOrInterfaceBodyDeclaration
 /ConstructorDeclaration[ count (.//ExplicitConstructorInvocation)=0 ]
    
              
  
		    
		    
	    
	    
        
        
        Example:
            
                    

public class Foo extends Bar{
 public Foo() {
  // call the constructor of Bar
  super();
 }
 public Foo(int code) {
  // do something with code
  this();
  // no problem with this
 }
}
