方法重載和方法重載是Java中實(shí)現(xiàn)多態(tài)的兩種機(jī)制。 1.方法重載發(fā)生在同一個(gè)類中，要求方法名相同但參數(shù)列表不同（參數(shù)數(shù)量、類型或順序），屬於編譯時(shí)多態(tài)，返回類型可不同但不能僅靠返回類型重載，可有不同的訪問修飾符和異常聲明；2.方法重寫發(fā)生在繼承關(guān)係中，子類提供父類已有方法的具體實(shí)現(xiàn)，要求方法簽名相同，返回類型兼容，訪問修飾符不能更嚴(yán)格，屬於運(yùn)行時(shí)多態(tài)，必須使用實(shí)例方法且可通過@Override註解確保正確重寫。兩者共同提升代碼可讀性和可擴(kuò)展性。

U盤顯示容量小於標(biāo)稱值是正常的，主要因計(jì)算方式和系統(tǒng)佔(zhàn)用導(dǎo)致：1.廠商按十進(jìn)制（1000進(jìn)制）標(biāo)註容量，而電腦按二進(jìn)制（1024進(jìn)制）計(jì)算，如32GB標(biāo)稱容量實(shí)際顯示約29.8GB；2.文件系統(tǒng)格式化後的開銷、隱藏文件及廠商預(yù)留空間（用於固件或磨損均衡）會(huì)佔(zhàn)用部分容量；3.若容量差異過大（如標(biāo)32GB僅顯示15GB），可能是假冒產(chǎn)品，可用H2testw或F3工具檢測真實(shí)容量，建議通過正規(guī)渠道購買知名品牌以避免此類問題。
