Answer:
enable the used ports in the router with their respective IP address and only the connected ports in the switch. Allow configure the STP on the switch
Explanation:
Network switches are used to connect a group of computer devices in a network LAN. It is automatically enabled when a port is connected and creates a MAC address table of the computers connected to it. STP or spanning-tree protocol is a protocol used to prevent looping in a switch. Unused ports can be disabled for security reasons.
A router is a network device that is used to forward packets between networks. All used ports in a router must be enabled and configured with an IP address and subnet mask.
Classes called child classes or subclasses inherit methods and variables
Answer:
public static boolean beginsWithZ(String word){
if(string == null || string.length() == 0)
return 0;
if(word.charAt(0) == 'Z' || word.charAt(0) == 'z')
return 1;
else
return 0;
}
Explanation:
This method is a boolean method, meaning it returns true if the string begins with Z or z and false otherwise. So:
The Java command charAt() let's you find the character at each position of the string, so i use it.
public static boolean beginsWithZ(String word){
if(string == null || string.length() == 0)
return 0;
if(word.charAt(0) == 'Z' || word.charAt(0) == 'z')
return 1;
else
return 0;
}
Answer: the continue numbering feature can be used to maintain the numbering order in a list and the restart at 1 feature can be used to make a new list
Explanation:
Answer:
The above code print the text at three times.
Explanation:
- It is because the above code has one loop which executes three times. The loop executes for the value of i = 0,1 and 10.
- when the value of i is 0 then "++i" will increase the value 1 and the text will be printed.
- If the value of i=1, then the value of i is 2 in the second iteration and the again the text is printed, then the if condition gives the true result and the value of i will be 10.
- Then the loop executes for the last time when the value of i is 10.Then the value will be 11 because of the increment operator and the text will be printed for the third time.
- Then the while loop is not true for the 11 value of i and the loop will get terminated.
