可能會創建一個數組的數組？

Question

是否可以創建一個數組的數組？我想要做的是基本上做一個沒有重複的另一個數組的數組。

例如：

String[] colour ={"blue","blue","red","blue","red","red","orange","yellow","purple","green","blue"}; 

，然後使新的數組從字符串[]顏色分爲：

String[] uniqueColour = {"blue","red","orange","yellow","purple","green"} 

使用的函數，並且不只是聲明嗎？因爲可以說我改變的String []色彩的所有值，並把它變成

String[] Fruits = {"Apple","Banana","Orange","Tomato","Apple","Banana"} 

則沒有做或其他任何變動功能應該創建

String[] uniqueColour ={"Apple","Banana","Orange","Tomato"} 

難道這樣的事情存在？抱歉，添麻煩了。而且我也是java新手。

謝謝任何​​能夠貢獻或幫助我的人。

編輯： 好了，所以通過使用這樣的： - 由於門把手的回答

Set<String> uniqueSet = new HashSet<String>(Arrays.asList(colour)); 
String[] uniqueColours = uniqueSet.toArray(new String[0]); 

我怎麼會再嘗試將其顯示爲：

Blue 
Red 
Yellow 
Green 
Purple 
ect 

，而不是[Blue,Red,Yellow,Green,Purple,etc]

Answer 1

使用一個Set刪除重複項：

Set<String> uniqueSet = new HashSet<String>(Arrays.asList(colour)); 
String[] uniqueColours = uniqueSet.toArray(new String[0]); 

要在你想要的方式顯示出來：

for (String s : uniqueColors) System.out.println(s);
