Q1. Write a Java program that performs the following steps:  Prompt the user to input two positive integers: firstNum and secondNum (firstNum must be less than secondNum). Output all odd numbers between firstNum and secondNum. Output the sum of all even numbers between firstNum and secondNum. Output the sum of the square of the odd numbers between firstNum and secondNum.

Q1.

1. Write a Java program that performs the following steps: 
2. Prompt the user to input two positive integers: firstNum and secondNum

(firstNum must be less than secondNum).

1. Output all odd numbers between firstNum and secondNum.

• Output the sum of all even numbers between firstNum and

secondNum.

1. Output the sum of the square of the odd numbers between firstNum

and secondNum.

Q2.

1.  write a Java program to encode a name by creating an array of integers.
2. Write Java method called encodeName that takes a name as a string (without spacing and all lower case) and returns an array of integers of the same size as name whose elements are the number in the alphabet of the corresponding character in name (starting from zero). For example, calling this method with name = “aabed” it should return [0, 0, 1, 4, 3].
3. Write a printArray method that prints all the elements of an array of integers in one line.

• Write a main method that calls encodeName and printArray methods to print the array corresponding to your name.

Q3.

1. Write a Java program that prompts the user to enter a line of text and outputs the number of digits, the number of lower case letter and the number of upper case letter in that text.
