如何用空格左键填充整数?
问题描述：
如何设置不带前导零的整数值?我尝试使用十进制格式，但无法获得准确的结果:
How to format an Integer value without leading zero? I tried using decimal format but I can't achieve exact result:
DecimalFormat dFormat=new DecimalFormat("000");
mTotalNoCallsLbl.setText(""+dFormat.format(mTotalNoOfCallsCount));
mTotalNoOfSmsLbl.setText(""+dFormat.format(mTotalNoOfSmsCount));
mSelectedNoOfCallsLbl.setText(""+dFormat.format(mSelectedNoOfCallLogsCount));
mSelectedNoOfSmsLbl.setText(""+dFormat.format(mSelectedNoOfSmsCount));
我得到这些输出:
500
004
011
234
但是我想要这些:
500
4
11
234
我的问题是如何用空格替换零?
My question is how to replace the zeroes with spaces?
答
看起来像您想用空格左键填充，所以也许您想要:
Looks like you want to left-pad with spaces, so perhaps you want:
String.format("%3d", yourInteger);
例如:
int[] values = { 500, 4, 11, 234 };
for (int v : values) {
System.out.println(String.format("%3d", v));
}
输出:
500
4
11
234
