我有一個簡單計算代碼,計算關於盒體積(長×寬×高):的java設置雙精度值格式
ActionListener volListener = new ActionListener() {
public void actionPerformed(ActionEvent e) {
try{
String L = long.getText();
String W = width.getText();
String H = height.getText();
double parseL = Double.parseDouble(L);
double parseW = Double.parseDouble(W);
double parseH = Double.parseDouble(H);
double volResult = parseL*parseW*parseH;
txtAreaOut.append("Volume : " + volResult + "\n");
long.setText("");
width.setText("");
height.setText("");
}catch(NumberFormatException nfe){
String fault = nfe.getMessage();
infoBox(fault, " " + nfe.getClass());
}
}
};
如果「volResult」返回大量,例如9.0408284742E7, 和我希望這樣9.040.828.474結果...
代碼如何?..
在這裏檢查,有答案顯示整數和/或格式數字字符串,如果你想逗號。 http://stackoverflow.com/questions/9602444/force-a-double-to-write-the-whole-number – theguywhodreams
這是重複的很多問題是重複的另一個問題,我甚至不知道要選擇哪個... – zubergu
