5) Write a program in java to check whether the entered character is alphabet, digit or space character. If it is alphabet then print whether it is capital or small alphabet. Also change the alphabet into the reverse case.

import java.io.*;
class Check

public static void main(String args[]) throws IOException
char ch;
BufferedReader inputstream =new BufferedReader(new InputStreamReader(System.in));

System.out.println(“Enter Any Character:-”);

ch=(char) inputstream.read();

System.out.println(“Entered Character is Digit”);
else if(Character.isUpperCase(ch))
System.out.println(“Entered Character is Upper case”);
System.out.println(“Lower Case Character is:-”+Character.toLowerCase(ch));
else if(Character.isLowerCase(ch))
System.out.println(“Entered Character is Lower Case”);
System.out.println(“Upper Case Character is:-”+Character.toUpperCase(ch));
System.out.println(“Entered Character is special char”);
