我已經使用SimpleDateFormat創建了一個日期，我該如何轉換成字符串？

Question

newDate =(newDaysAdded+"/"+month+"/"+year); 
SimpleDateFormat date = new SimpleDateFormat("dd/MM/yyyy"); 
try { 
    Date newDateOne = date.parse(newDate); 

當我嘗試：

view.writeToScreen(newDateOne); 

我得到的錯誤：

Incompatible types: Date cannot be converted to String. 

這裏是writeToScreen方法：

void writeToScreen(String s); 

從那裏，我不能變成

然而一個字符串，我試過了： String test = Date.toString（newDateOne）;

任何人都可以幫忙嗎？

Answer 1

基於現有的代碼，你可以使用：

writeToScreen (date.format(newDateOne)); 

Answer 2

變化

view.writeToScreen(newDateOne); 

到

view.writeToScreen(newDateOne.toString()); 

Answer 3

嘗試看看所有的方法......無論是在API中doc甚至在代碼編輯器中的intellisense中

public static void main(String[] args) { 
     String newDaysAdded = "05"; 
     String month = "04"; 
     String year = "2014"; 
     String newDateString = (newDaysAdded+"/"+month+"/"+year); 

     SimpleDateFormat SDF = new SimpleDateFormat("dd/MM/yyyy"); 
     try { 
      Date newDate = SDF.parse(newDateString); //Takes string and convert it to date 

      //If i understand the question you dont just want to print it as a date... 
      System.out.println(newDate); //Sat Apr 05 00:00:00 CAT 2014 

      //You want to print it as a string inf the format you specified in the SDT 
      System.out.println(SDF.format(newDate)); //Print as in05/04/2014 
     } catch (ParseException e) { 
      e.printStackTrace(); 
     } 
    }
