本文整理了Java中java.lang.String.concat()方法的一些代码示例，展示了String.concat()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。String.concat()方法的具体详情如下：
包路径：java.lang.String
类名称：String
方法名：concat

String.concat介绍

[英]Concatenates the specified string to the end of this string.

If the length of the argument string is 0, then this String object is returned. Otherwise, a new String object is created, representing a character sequence that is the concatenation of the character sequence represented by this String object and the character sequence represented by the argument string.

Examples:

"cares".concat("s") returns "caress" 
"to".concat("get").concat("her") returns "together"

[中]将指定的字符串连接到此字符串的结尾。
如果参数字符串的长度为0，则返回此String对象。否则，将创建一个新的String对象，该对象表示一个字符序列，该字符序列是此String对象表示的字符序列与参数字符串表示的字符序列的串联。
示例：

"cares".concat("s") returns "caress" 
"to".concat("get").concat("her") returns "together"
