-the main difference is that a method is doing some business logic e.g. and a constructor is there to create a object on the heap memory. In the constructor you can set attributes of your object.
- A constructor has no return type.
- When a constructor is called and you do not call explicitly a super constructor then java will call the super constructor of the super class. (depending on what you extend your class, default is java.lang.Object)
- a constructor cannot be inherited
This are the main things i think

hi
1)constructors needs to be with the same name as the class
2)they can not return a value
3)you can not inherit a constroctor from a perent calss

third point is tricky...U are actually inheriting the constructors...only difference is that you cant override it in the subclass unlike other public methods.

No. Only members of one class can be inherited by a descendant class. Constructors are not members and they are not inherited.
From The JLS:
Constructor declarations are not members. They are never inherited and therefore are not subject to hiding or overriding.
