Write a program that uses while loops to perform the following steps : a. Prompt the use to input two integers : FirstNum and secondNum.( FirstNum must be less than secondNum.) b. Output all the odd numbers between firstNum and secondNum inclusive. c. Output the sum of all the ven number between FirstNum and secondNum inclusive. d. Output all the numbers and their squares between 1-10. e. Output the sum of the squares of all the odd numbers between firstNum and secondNum inclusive f. Output all the uppercase letters.

Here is your required code:

import java.util.*;
public class NumberExample{
    public static void main(String[]args){
        int sum=0,sumSquares=0;
        int num1=0,num2=0;
    Scanner input=new Scanner(System.in);
    System.out.print("Enter First Number: ");
     num1=input.nextInt();

    System.out.print("Enter Second Number: ");
     num2=input.nextInt();

    if(num1>num2){
    System.out.print("Your First Number is greater than second.So Please re-enter: ");
    num1=input.nextInt();
    }
    else{
        System.out.println("Odd Numbers: ");
while(num1 <= num2) {
if(num1%2 != 0) {
System.out.println(num1);
sumSquares+=(num1*num1);
}
if(num1%2 == 0) {
sum+=num1;
}
num1++;
}
System.out.println("Sum Of Even Numbers: "+sum);
System.out.println("Numbers and their squares between 1 and 10");
int i=1;
while(i <= 10) {
System.out.println(i+"    "+(i*i));
i++;
}
System.out.println("Sum Of square of odd Numbers: "+sumSquares);
}
    }
}
