Java – given a list of IP addresses, how do you find min, max?

In Java, I have an ArrayList of IP addresses How do I find the minimum and maximum values?

I have used collection Min () but it doesn't work. The following conditions are given:

192.168.0.1  <--min 
192.168.0.250
192.168.0.9  <--max

How can I return

192.168.0.1  <--min
192.168.0.250 <--max

Replace?

ArrayList is retrieved from the database I need to do this every tick (every tick interval is 5 seconds) The maximum number of IP addresses may reach 300

Solution

Converts IP addresses to long integers and sorts them You can use binary arithmetic / operators to convert 192.168 0.1 to integer:

( 192 << 24 ) + ( 168 << 16 ) + ( 0 << 8 ) + ( 1 << 0 )

wait. Please read the following notes about using the correct data type
