Aug 06, 2025 am 07:42 AM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。
