ICSE Java Programming String Edit 2018 Q6

Write a program to accept a string in lower case and change the first letter of every word to upper case.
Display the new string.
Sample input: we are in cyber world.
Sample output: We Are In Cyber World.

ENTER A STRING IN LOWER CASE:

 flag = False

while (flag == False):

    msg = str(input("Enter a string in lower case:"))

    if(msg.islower() == False):

        print("Every character must be in lower case, try again:")

        flag = False

    else:

        flag = True

outputmsg = []

outputmsg.append(msg[0].upper())

for k in range (1,len(msg)):

    if (msg[k-1] == ' '):

        outputmsg.append(msg[k].upper())

    else:

        outputmsg.append(msg[k])

string = ""

for i in range (len(outputmsg)):

    string += outputmsg[i]

print(string)

 import java.util.*;

public class ICSEJava {

    public static void main(String[] args) {

        String input;

        char[] output;

        Scanner in = new Scanner(System.in);

        do {

            System.out.println("Enter a string in lower case:");

            input = in.nextLine();

            flag = false;

            for (int i = 0; i < input.length(); i++) {

                if (input.charAt(i) >= 65 && input.charAt(i) <= 90) {

                    System.out.println("Every character must be in lower case, try again:");

                    flag = true;

                    break;

                output[k] = (input.charAt(k));

                output[k + 1] = Character.toUpperCase(input.charAt(k + 1));

                k += 1;

            } else

ICSE 2018 Pronic Number Question 5

Write a program to input a positive number and check and print whether it is a Pronic number or not. (Pronic number is a number which can be written as product of two consecutive integers)
Example:
12 = 3 x 4
42 = 6 x 7
20 = 4 x 5

ENTER A POSITIVE INTEGER:

 class PronicNumber:

    def pronicRepresentation(self):

        print(self.__number," is a Pronic Number. ",self.__number," = ",self.__index," x ",(self.__index+1))

    def isPronic(self):

        i = 1

        while (i*(i+1) <= self.__number):

            if(i*(i+1) == self.__number):

                self.__flag = True

                self.__index = i

                break

            i +=1

        return(self.__flag)

    def __init__(self,n):

        self.__number = n

    __number = 0

    __index = -1

    __flag = False

n = int(input("Enter a positive integer."))

obj = PronicNumber(n)

if(obj.isPronic()):

    obj.pronicRepresentation()

else:

    print(n," is not a Pronic Number.")

 import java.util.Scanner;

public class ICSEJava {

    public static void main(String[] args) {

        int n;

        Scanner in = new Scanner(System.in);

        System.out.println("Enter a positive integer:");

        n = in.nextInt();

        PronicNumber obj = new PronicNumber(n);

        if(obj.isPronic())

            obj.pronicRepresentation();

        else

            System.out.println(n+" is not a Pronic Number");

        in.close();

    }

}

class PronicNumber {

    public void pronicRepresentation() {

        System.out.println(number+" is a Pronic Number. "+number+" = "+index+" x "+(index+1));        

    }

    public boolean isPronic() {

        int i = 1;

        while(i*(i+1) <= number){

            if(i*(i+1) == number) {

                flag = true;

                index = i;

                break;

            }

            i++;

        }

        return(flag);

    }

    PronicNumber(int n){

        number = n;

        flag = false;

        index = -1;

    }

    int number;

    int index;

    boolean flag;
