Write a java program that reads n of type integer and calculates and prints the value sum of squares of odd numbers from 1 to n: s = 12 + 32 + 52 + +n? ... Note: if the user enters a negative value for n, the program should stop directly and prints an error message. Sample run: Enter n: 4 The sum of squares from 1 to 4: 10

Computer Science please in java. must use while loop.

Using python, please explain 1: A positive integer greater than 1 is said to be prime if it has no divisors other than 1 and itself. A positive integer greater than 1 is composite if it is not prime. Write a program that asks the user to enter an integer greater than 1, then displays all of the prime numbers that are less than or equal to the number entered  The program should work as follows: Once the user has entered a number, the program should populate a list with all of the integers from 2 up through the value entered. The program should then use a loop to step through the list. The loop should pass each element to a function that displays the element whether it is a prime number.

plz explain python
