Primitive values do not share state with other primitive values.jls 4.2
Don't feel bad, it's not an easy statement for a native English speaker either.

The state of an object typically contains
references to other objects.

However a primitive cannot contain anything but the primitive value of that type. It cannot contain references to another primitive.

The idea is simple, and you may likely understand it already. An example that further illustrates the concept:
If a variable i of type int is declared and given it an initial value 0, and another int variable j is declared and assigned the value of i, then both variables would have the value 0. If i is later assigned a different value such as 1, the value of j is not affected - j would still be 0.Making sense?
