我遇到問題。我有這個計劃，我應該創建，它應該讀取兩個測驗的成績，這兩個測驗的總和等於25％的學生總分，期中考試是25％的學生成績和期末考試是總等級的50％。當我運行程序時，除了第一次測驗分數爲7分，第二次測驗分數爲8分，中期分數爲90分以及最終分數爲80分時，除了總分爲81.25％之外，其他所有內容都可以，但是會顯示.8125並自動給學生F.我不知道如何修復它....需要關於java分級程序的幫助嗎？我需要製作一個程序，讀取學生總成績的百分比

我認爲人們看你的標題，看到第一個兩句話，缺乏資本化，並下調投票你的問題認爲你要求的代碼，並沒有花時間來正確地格式化你的問題。您可能想要編輯它。 – DoubleDouble
是的，我就像爲什麼我得到像一百萬倒票？我並沒有乞求人們尋找類似這裏數百萬人的代碼，我只是需要幫助。 – Madridista94
