The Internet began as a US Department of Defense network named Advanced Research Project Agency Network (ARPANET) funded by the Advanced Research Project Agency (ARPA, later DARPA). In the 1970s, universities and other educational institutions began sharing this technology. The network grew as more and more users began sharing information.However, the information being shared on this network was very limited because of its government ties. The ARPANET was decommissioned in 1990. This move was followed by the commercialization of the Internet, which allowed it to carry business and personal traffic.
Answer:
import java.util.Scanner;
public class CharTestt { public static void main(String[] args) { System.out.println("Please enter a character "); Scanner input = new Scanner(System.in); char letterStart = input.next().charAt(0); char thenextChar = (char)(letterStart+1); System.out.print(letterStart); System.out.println(thenextChar);
}
}
Explanation:
Import Scanner Class
Prompt user to enter a character
Read and save user's input in a variable char letterStart = input.next().charAt(0);
Knowing that the next character using ASCII is +1, create a new character variable and add 1
print the character entered and the new character all on same line without spaces
