I am very much confused between instance variables and property. I have read number of posts regarding this but still i am not clear about it.
I am from JAVA background and what i infer from objective C documentation is that a property is similar to JAVA BEAN CLASS (one having getter and setter of instance varibles). A property can accessed from other classes through its getter and setter methods while an instance variable is private and cannot be accessed from other classes.

Am i right in thinking in this direction ?

    The parallel with Java is very good. The only difference is that Objective C provides a way to access a property as if it were a variable, and Java does not. The other difference is that in Objective C you can synthesize properties, while in Java you need to write your getters and setters manually.

    Property is a “syntactic sugar” over a getter method or a pair of a getter and a setter methods. Properties are often (but not always) backed by an instance variable, but they can be implemented in any way that you can implement a parameterless instance method.
