java里面使用string.format实现空格右填充代码如下：
package cn.com.songjy
import java.text.NumberFormat
public class NumberFormatTest {
public static void main(String[] args) {
int i = 1
NumberFormat nf = NumberFormat.getInstance()
nf.setGroupingUsed(false)
nf.setMaximumIntegerDigits(4)
nf.setMinimumIntegerDigits(4)
System.out.println(nf.format(i))
}
}
public class TestStringFormat {
public static void main(String[] args) {
int youNumber = 1
String str = String.format("%04d", youNumber)
System.out.println(str)// 0001
}
}
private static final String STR_FORMAT = "0000"
public static String haoAddOne_2(String liuShuiHao){
Integer intHao = Integer.parseInt(liuShuiHao)
intHao++
DecimalFormat df = new DecimalFormat(STR_FORMAT)
return df.format(intHao)
}
