如何將字符串列表轉換爲arraylist並單獨調用它？

Question

我有一個來自循環語句的字符串列表，我不知道如何使它成爲一個ArrayList然後單獨調用字符串。這裏是while語句：

try { 
    toDate=format.parse(str4); 
    java.util.Date newValue= new SimpleDateFormat(OLD_FORMAT).parse(str4); 
    String newValue2 = new SimpleDateFormat(NEW_FORMAT).format(newValue); 
    // System.out.println(newValue2); 
} catch (ParseException e1) { 
    // TODO Auto-generated catch block 
    e1.printStackTrace(); 
} 


//change the format of toDate 
try { 
    newDateString=format.parse(str5); 
    java.util.Date newqwe = new SimpleDateFormat(OLD_FORMAT).parse(str5); 
    String newqwe2=new SimpleDateFormat (NEW_FORMAT).format(newqwe); 
    //System.out.println(newqwe2); 
} catch (ParseException e1) { 
    // TODO Auto-generated catch block 
    e1.printStackTrace(); 
} 

//get the days between two dates then print it 
Calendar cal2 = Calendar.getInstance(); 
cal2.setTime(toDate); 
while (cal2.getTime().before(newDateString)) { 
    cal2.add(Calendar.DATE, 1); 
    String datelist=(format.format(cal2.getTime())); 

STR4是一個標誌，是一個日期相同STR5，當按鈕被點擊從循環語句後面的字符串將是這樣的：

2013-05-03 
2013-05-04 
2013-05-05 
2013-05-05 
2013-05-06 
2013-05-07 
2013-05-08 
2013-05-09 
2013-05-10 
2013-05-11 
2013-05-12 
2013-05-13 
2013-05-14 
2013-05-15 
2013-05-16 
2013-05-17 

Answer 1

List<String> list = new ArrayList<String>(); 

list.add("2013-05-03"); 
list.add("2013-05-04"); 
........etc 

for(String str:list) 
    System.out.prinltn(str); // prints all the strings in list 


System.out.println(list.get(index)); // prints string at specified index
