Java錯誤：構造函數C17PacketCustomPayload（String，byte []）未定義

-2

爲什麼我得到這個錯誤？Java錯誤：構造函數C17PacketCustomPayload（String，byte []）未定義

The constructor C17PacketCustomPayload(String, byte[]) is undefined

Java代碼：

     ByteBuffer.wrap(buffer).putDouble(reachValue`enter code here`); 

     return buffer; 
    } 
}

什麼構造函數_does_'C17PacketCustomPayload'有？ –

我猜測這意味着該構造函數沒有定義。問題是什麼？ – EJoshuaS

我猜你在這裏得到你的錯誤：

return new C17PacketCustomPayload("reach", spoofedReachValue);

它說，構造函數是不確定的，這意味着該類C17PacketCustomPayload不有一個構造函數將一個字符串和/或byte []作爲參數。如果你創建了這個類自己，那麼你需要添加看起來像這樣

public C17PacketCustomPayload(String string, byte[] bytes){ 
//add behavior here 
}

如果你沒有創建這個類，但僅僅是進口，那麼你需要查找正是這個參數構造函數取和方法相應地修復它。

Why I am getting this error?

從這些逆向工程javadocs可以明顯地看出答案。

Constructors: 

C17PacketCustomPayload() 
C17PacketCustomPayload(java.lang.String p1, PacketBuffer p1)

在你的代碼，構造函數調用的第二個參數必須是一個PacketBuffer對象，而不是byte[]。
