Answer:
The code to this question can be given as:
Code:
//define code.
//conditional statements.
if (Character.isLetter(passCode.charAt(0))) //if block
{
System.out.println("Alphabetic at 0"); //print message.
}
if (Character.isLetter(passCode.charAt(1))) //if block
{
System.out.println("Alphabetic at 1"); //print message.
}
Explanation:
In this code, we define conditional statement and we use two if blocks. In both if blocks we use isLetter() function and charAt() function. The isLetter() function checks the inserted value is letter or not inside this function we use charAt() function that checks inserted value index 1 and 2 is the character or not.
- In first if block we pass the user input value and check the condition that if the inserted value is a character and its index is 0 so, it will print Alphabetic at 0.
- In second if block we pass the user input value and check the condition that if the inserted value is a character and its index is 1 so, it will print Alphabetic at 1.
Answer:
SSIDs : service state identifiers are used to beacon for connect from an access point or wireless router. They are used to request for authentication in a wireless network.
Channels used: this is the frequency range used by a wireless network. It is spaced to avoid collision.
Ap names is the name of the wireless access point that is used to identify a beacon in a workstation. Bluetooth is a short range private network between two devices.
RFID: radio frequency identifier or identification is a chip that hold information of an individual electronically.
Explanation:
These are some examples of wireless communication devices.
Black is the darkest color, the result of the absence or complete absorption of visible light. It is an achromatic color, literally a color without hue, like white and gray. It is often used symbolically or figuratively to represent darkness, while white represents light. This should help. If wrong, I am sorry.
