Write an interactive Java program to calculate how many years it takes to double your fix-amount of savings in a bank. Suppose the interest rate is fixed.
For example, if user saves 1000 dollars into bank, so at bank interest rate 7%, it may take at least 11 years to have the balance become 2000 dollars. Please write a command-line application to assign the letter grades to students based on their scores. Your program should first ask the number of students in the class. For each user, it should ask the name of the student and his/her average score. Then, it should calculate the letter grade, and display the name and the letter grade of the student just entered. It should calculate the letter grades as many times as the number of the students given at the beginning of the program.
Your program should calculate the letter grade as follows:
For average scores from 90 to 100, the letter grade should be “A”.
For average scores from 80 to 89, the letter grade should be

好累啊，看了一大会终于有点头绪了，很简单的嘛，case一下就完事了啊。前面的银行的用数学表达式表示一下不就ok了。代码自己写吧！
我觉得你不是不会写这个。，而是读不懂英文把
全是英文哦
