Questions:
1. Write a Java program to get a number from the user and print whether it is
positive or negative.
2. Take three numbers from the user and print the greatest number.
3. Write a Java program that reads a floating-point number and prints "zero" if the
number is zero. Otherwise, print "positive" or "negative".
Add "small" if the absolute value of the number is less than 1, or "large" if it
exceeds 1,000,000.
4. Write a Java program that takes the user to provide a single character from the
alphabet.
Print Vowel or Consonant, depending on the user input.
If the user input is not a letter (between a and z or A and Z), or is a string of length
> 1, print an error message.
