本文整理了Java中java.lang.String.replace()方法的一些代码示例，展示了String.replace()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.replace()方法的具体详情如下：
包路径：java.lang.String
类名称：String
方法名：replace
[英]Returns a new string resulting from replacing all occurrences of oldChar in this string with newChar.
If the character oldChar does not occur in the character sequence represented by this String object, then a reference to this String object is returned. Otherwise, a new String object is created that represents a character sequence identical to the character sequence represented by this String object, except that every occurrence of oldChar is replaced by an occurrence of newChar.
Examples:
"mesquite in your cellar".replace('e', 'o')
returns "mosquito in your collar"
"the war of baronets".replace('r', 'y')
returns "the way of bayonets"
"sparring with a purple porpoise".replace('p', 't')
returns "starring with a turtle tortoise"
"JonL".replace('q', 'x') returns "JonL" (no change)[中]返回将此字符串中所有出现的oldChar替换为newChar后生成的新字符串。
如果字符oldChar未出现在此String对象表示的字符序列中，则返回对该String对象的引用。否则，将创建一个新的String对象，该对象表示与此String对象表示的字符序列相同的字符序列，但oldChar的每一次出现都被newChar替换。
示例：
"mesquite in your cellar".replace('e', 'o')
returns "mosquito in your collar"
"the war of baronets".replace('r', 'y')
returns "the way of bayonets"
"sparring with a purple porpoise".replace('p', 't')
returns "starring with a turtle tortoise"
"JonL".replace('q', 'x') returns "JonL" (no change)代码示例来源：origin: spring-projects/spring-framework
