兩個數組合併爲一個通過的第一個

Question

我有兩個列表這樣的數字：

1. [apple, orange] 
2. [cyan, magenta, yellow, black] 

我想要的算法打印這樣的：

1. [apple:cyan,magenta] 
2. [orange:yellow, black] 

我在做什麼錯？

public static void main(String[] args) throws IOException { 
String file_name_Colors = "D:/colors.txt"; 
String file_name_Fruts = "D:/fruts.txt"; 
Scanner input = new Scanner(System.in); 
int number_Colors; 
int number_Fruts; 
number_Colors = input.nextInt(); 
number_Fruts = input.nextInt(); 
try{ 
ReadFileColors fileColors = new ReadFileColors(file_name_Colors, number_Colors); 
ReadFileFruts fileFruts = new ReadFileFruts(file_name_Fruts, number_Fruts); 
String[] aryLines = fileColors.OpenFileColors(); 
String[] aryLinesFruts = fileFruts.OpenFileFruts(); 
List<String> listColorPleaseTY = new ArrayList<>(); 
List<String> listFruts_Fruts = new ArrayList<>(); 
int numberColorPlease; 
int numberFrutsPlease; 
for(numberColorPlease=0; numberColorPlease<aryLines.length; numberColorPlease++){ 
    listColorPleaseTY.add(aryLines[numberColorPlease]); 
} 
for(numberFrutsPlease=0; numberFrutsPlease<aryLinesFruts.length; numberFrutsPlease++){ 
    listFruts_Fruts.add(aryLinesFruts[numberFrutsPlease]); 
} 
System.out.println(listFruts_Fruts); 
System.out.println(listColorPleaseTY); 

List<String> subItemslistnewone = new ArrayList<String>(listColorPleaseTY.subList(0, number_Colors)); 
System.out.println(subItemslistnewone); 
    } catch (IOException e){ System.out.println(e.getMessage()); } 
}

我不確定分配標準，你需要這樣的東西嗎？

public static void main(String[] args) { 

    List<String> fruits = Arrays.asList("apple","orange"); 
    List<String> colours = Arrays.asList("cyan","magenta","yellow","black"); 
    List<String> result = new ArrayList<>(fruits.size()); 
    for (int i = 0; i < fruits.size(); i++) { 
     StringBuilder sb = new StringBuilder(); 
     sb.append(fruits.get(i)); 
     sb.append(":"); 
     int begin = (i*colours.size())/fruits.size() + 1; 
     int end = ((i+1)*colours.size())/fruits.size(); 
     sb.append(colours.get(begin-1)); 
     for (int j = begin; j < end; j++) { 
      sb.append(","); 
      sb.append(colours.get(j)); 
     } 
     result.add(sb.toString()); 
    } 
    for (int i = 0; i < result.size(); i++) { 
     System.out.println((i+1)+". ["+result.get(i)+"]"); 
    } 
}
