For this exercise, you will use the expressions from the box below to fill in the gaps in the given Java program. The requirements for the program are as follows:

Write a program that asks the user to enter an integer. The program will then find the sum of all the integers up through that number. The program should display that sum to the user with an appropriate label. The program should reject any integers less than $1$ using an input validation loop $($while$).$

The sum of an integer is all the integers between $1$ and a given number added up$.$ For example, if the user enter $4,$ then the sum of integers would be: $1+2+3+4=10.$
