this vs super in Java

 this vs super

• this can be used to read all members declared within the class
• this can all be used to read all inherited members in the direct parent class
• this can be used in an instance method, constructor and instance block
• this cannot be used in a static method or static initializer block
• super can read only inherited members declared in the parent class
• super excludes any members found in the current class
• super always refer to the direct parent
• this() can be used to invoke current class constructor
• super() invokes constructor of the parent class
• if we choose to call this() or super() , it must be the first statement in the constructor body. There can be only one call.
• this refers to an instance of the class, while this() refers to a constructor call within the class
• Java compiler automatically inserts a call to the no-argument constructor super() if we do not explicitly call this() or super() as the first line of a constructor.
• static methods do not have reference to this or super
