Lab Assignment 7: “if else Statements”

Write a program that will give the grade of the student based on the percentage he got in the course. 

Use the following criteria for assigning grades:

Grade = A  ( when percentage >= 60)
Grade = B  ( when percentage >= 50 and percentage < 60)
Grade = C  ( when percentage >= 40 and percentage < 50)
Grade = D  ( when percentage >= 30 and percentage < 40)
Grade = E  ( when percentage >= 20 and percentage < 30)

Write your program using the if else statements. Prompt the user
to enter the percentage he received in the course. Create just one file
named "StudentGrade.java" and write all statements inside the main method.
