如何将数字格式化为相同的位数，0填充?

2022-01-15 00:00:00 format java

我有几个不同长度的字符串

I have several strings of different length

"2323" "245" "353352"

我需要将它们转换为相同大小的字符串，例如:

I need to convert them to string of the same size such as:

"0002323" "0000245" "0353352"

如何在每个字符串前面自动添加正确数量的 0?

How can I automatically add the correct number of 0s in front of each string ?

谢谢

推荐答案

使用String.format:

Integer i = Integer.valueOf(src); String format = "%1$07d"; String result = String.format(format, i);
