int overrun issue

Hello I have a question. int has a range from -2 to the power of 32 to 2 to the power of 32 -1. If I now assign a int variable to 3 * 1 * 10 to the power of 9, System.out.println will give me an overrun. Now the Question is . What number do i get? does it end with 5 or 6? With the IDE i get a 6 but when i count it with Geogebra i get 5. thanks for your help

Sanoj i don't get what do you mean by 5 or 6..? Integer range in java is -2147483648 to 2147483647. If you exceed the value of max value then you will get the number count from minimum value.. Add an example for your description...

Int has a range -2 in power of 31 to 2 in power of 31 - 1, btw. 2 in power of 32 is a total number of values.

@ Jayakrishna with 5 or 6 i mean the last digit of the result when you calculate 3*1 *10^9. What result do you get? -1294967295 or -1294967296

With 3*10^8 only you get correct result, and 3*10^9 you are getting overrun.. 6 getting but 5 or 6 both overrun values.. What is the difference..
