Employee has variable: int i = 5
and method: int getI()
Manager has variable: int i = 10
and same method.

When this is issued:
Employee m = new Manager();
What happened here?
What I know is the object m's variable is in Employee's but the method is Manager's.
What is the concept behind it?
Thanks.

Basically, variables are accessed according to the declared type of the variable and methods are invoked according to the runtime type of the variable.
I invite you to read the following JLS sections:
JLS 8.3.3 Examples of Field Declarations and JLS 8.4.6 Inheritance, Overriding, and Hiding
