本文整理了Java中com.google.common.base.Strings.padStart()方法的一些代码示例，展示了Strings.padStart()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Strings.padStart()方法的具体详情如下：
包路径：com.google.common.base.Strings
类名称：Strings
方法名：padStart

Strings.padStart介绍

[英]Returns a string, of length at least minLength, consisting of string prepended with as many copies of padChar as are necessary to reach that length. For example,

• padStart("7", 3, '0') returns "007"
• padStart("2010", 3, '0') returns "2010"

See java.util.Formatter for a richer set of formatting capabilities.
[中]返回一个长度至少为minLength的字符串，该字符串包含为达到该长度所需的尽可能多的padChar副本。例如
*padStart（“7”，3，'0'）返回“007”
*padStart（“2010”，3，'0'）返回“2010”
参见java。util。Formatter提供更丰富的格式化功能。
