When you call one of the Scanner class's methods to read a primitive value, such as nextInt or nextDouble, and then call the nex

Rzqust [24]

The answer is true.

Explanation:

The scanner class's methods are the methods in java.util, which allows the user to read values of various types. If the nextLine is issued after a numeric read and the numeric value is at the end of the line, nextLine returns the empty string.

The problem occurs when you click the enter key which is a new line \n character. nextInt() has only the integer but skips the new line \n.

To solve this problem, you have to add the input.nextLine() after reading the int it will consume the \n.

Hence, make input.nextLine(); call after input.nextint(); which reads till end of life.

Dima020 [189]

A DHCPv4 client use the broadcast IP address to send the initial DHCP discover packet when the client is looking for a DHCP server. 
A workstation will send a DHCPDISCOVER message to start the process of obtaining a valid IP address. The client does not know the addresses of DHCP servers, and that's why it sends the message via broadcast, with destination addresses of FF-FF-FF-FF-FF-FF and 255.255.255.255.

AN OBSTACLE OR BARRIER THAT MAY PREVENT YOU FROM ACCOMPLISHING YOUR GOAL IS:

marishachu [46]

Depends on what kind of goal.
If I gave a goal of eating 8 hot dogs then a barrier would be a physical will of your body to not eat more. It would be a limit your body can take so it’s different from a mental or other barrier.
If you wanted to cross an area of land but there is a fence in the way then that’s another type of barrier.
Or there are mental barriers. If you wanted to ask someone out to prom, you may be stopped by a mental barrier of self hatred. Feeling like you’re not good enough.

Hopefully this helps!
