定製的法國數字格式

我嘗試爲美國國家定製數字格式。到目前爲止它工作正常。定製的法國數字格式

// Not something I want. 
    NumberFormat numberFormat0 = NumberFormat.getNumberInstance(Locale.US);   
    System.out.println("US = " + numberFormat0.format(1234.0) + " (I wish to have 1,234.00)"); 
    System.out.println("US = " + numberFormat0.format(1234.567) + " (I wish to have 1,234.567)"); 
    System.out.println("US = " + numberFormat0.format(1234.5678) + " (I wish to have 1,234.568)\n"); 

    // Yes. Something I want :) 
    NumberFormat goodNumberFormat = new DecimalFormat("#,##0.00#"); 
    System.out.println("US = " + goodNumberFormat.format(1234.0) + " (I wish to have 1,234.00)"); 
    System.out.println("US = " + goodNumberFormat.format(1234.567) + " (I wish to have 1,234.567)"); 
    System.out.println("US = " + goodNumberFormat.format(1234.5678) + " (I wish to have 1,234.568)\n");

這是輸出。

US = 1,234 (I wish to have 1,234.00) 
US = 1,234.567 (I wish to have 1,234.567) 
US = 1,234.568 (I wish to have 1,234.568) 

US = 1,234.00 (I wish to have 1,234.00) 
US = 1,234.567 (I wish to have 1,234.567) 
US = 1,234.568 (I wish to have 1,234.568)

但是，對於法國來說，同樣的事情並不適用。因爲他們對.使用,，對於,使用「空格」。

我寫下面的代碼。

// Not something I want. 
    NumberFormat numberFormat1 = NumberFormat.getNumberInstance(Locale.FRANCE);   
    System.out.println("FRANCE = " + numberFormat1.format(1234.0) + " (I wish to have 1 234,00)"); 
    System.out.println("FRANCE = " + numberFormat1.format(1234.567) + " (I wish to have 1 234,567)"); 
    System.out.println("FRANCE = " + numberFormat1.format(1234.5678) + " (I wish to have 1 234,567)\n"); 

    // Exception in thread "main" java.lang.IllegalArgumentException: Malformed pattern "# ##0,00#" 
    NumberFormat goodNumberFormat1 = new DecimalFormat("# ##0,00#"); 
    System.out.println("FRANCE = " + goodNumberFormat1.format(1234.0) + " (I wish to have 1 234,00)"); 
    System.out.println("FRANCE = " + goodNumberFormat1.format(1234.567) + " (I wish to have 1 234,567)"); 
    System.out.println("FRANCE = " + goodNumberFormat1.format(1234.5678) + " (I wish to have 1 234,567)\n");

我收到以下錯誤。

FRANCE = 1 234 (I wish to have 1 234,00) 
FRANCE = 1 234,567 (I wish to have 1 234,567) 
FRANCE = 1 234,568 (I wish to have 1 234,567) 
Exception in thread "main" java.lang.IllegalArgumentException: Malformed pattern "# ##0,00#"

有什麼我可以做的，有上述定製的數字格式？

DecimalFormatSymbols dfs = DecimalFormatSymbols.getInstance(Locale.FRANCE); 
    NumberFormat goodNumberFormat = new DecimalFormat("#,##0.00#", dfs);

哦。我正在尋找具有數千個分隔符的「空間」。無論如何，你提出的解決方案是非常好的:) –

但我很好奇。如果德國人或法國人需要輸入「一點二」，他們是否在文本字段中鍵入「1,2」或「1.2」？將Integer.parseInt知道如何處理「1,2」？ –

@Ying Cheng CHEOK：我的解決方案適合您嗎？ – Tudor

Taddaaa！

DecimalFormatSymbols symbols = new DecimalFormatSymbols(); 
symbols.setDecimalSeparator(','); 
symbols.setGroupingSeparator(' '); 
NumberFormat goodNumberFormat1 = new DecimalFormat("#,##0.00#", symbols); 
System.out.println("FRANCE = " + goodNumberFormat1.format(1234.0) + " (I wish to have 1 234,00)"); 
System.out.println("FRANCE = " + goodNumberFormat1.format(1234.567) + " (I wish to have 1 234,567)"); 
System.out.println("FRANCE = " + goodNumberFormat1.format(1234.5678) + " (I wish to have 1 234,567)\n");
