Java數組我應該怎麼做才能從數組中讀取並顯示

Question

我應該怎麼做才能讀取數組並顯示它。 我嘗試使用這些，但input.next（）有錯誤;

import java.util.*; 

public class StringeEX 
{ 
    static Scanner input = new Scanner(System.in).useDelimiter("\r\n"); 


    public static void main(String[] args) 
    {  
    String ColourOne[] ={"Black","Brown","Red","Orange","Yellow","Green","Blue","Violet","Grey","White"}; 

    System.out.println("=========================================================="); 
    System.out.println("Black = 0," + "\t" + "Brown = 1," + "\t" + "Red = 2,"+ "\t" +"Orange = 3"); 
    System.out.println("Yellow = 4," + "\t" + "Green = 5," + "\t" + "Blue = 6," + "\t" +"Violet = 7"); 
    System.out.println("*** NOTE: ***"+"\t"+"Grey = 8,"+ "\t"+"white = 9"); 
    System.out.println("=========================================================="); 
    System.out.print("Please enter the number for the colour :"); 
    ColourOne = input.next(); 
for(int i = 0; i < ColourOne.length; i++) 
    System.out.println(ColourOne[i]); 

    } 
}

您正試圖將掃描儀輸入存儲到數組中。你應該指定一個單獨的變量。數組是零索引的，所以從數組中獲取值時使用ArrayName[someNumber]其中someNumber引用數組中的元素。第一元件從0開始

int i = input.nextInt(); 
System.out.println(ColourOne[i]);
