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