| I observed in SCJP 6 by kathy sierra and bert bates, that constructors will not be inherited from super class. Could you please clarify ? |

| constructors are NOT inherited in subclass.... | |

| Then how the super class constructor will be executed when we create the object for sub class. | |

| There is implicit call to base class constructor from each derived class constructor . Using keyword super() it calls base class constructor . "super();" is first statement of every derived class constructor either we provide explicitly or it is provided by JVM implicitly. | |

| class A { A( ) { } } class B extends A { } Can any one tell me that B's constructor is public or not? |

| If we are not providing any constructor compiler will place a default(no arg constructor) and call to it's super class constructor. Compiler provide following code for B class as follows. class B extends A{ B(){ super(); } } So constructors are not inherited although they are chained. |

| public class A { A() { System.out.println("A"); } } public class B extends A{ } 1. Class B if in the same package as of A. 2. Class B constructor default access is public. 3. Class B constructor will make call class A default constructor, here class A has explicit constructor declared with default access so it will be executed as a first thing in constructor B. 4. According to me option is correct at all. |

| Can anyone please explain about initialization of a float object. Meaning of these two lines:. Float f1[ ], f2[ ]; F1 = new float[10]; |

| One constructor cannot inherit another constructor in any case. | |
