Java 字符串拆分/删除 n 个特殊字符部分

Question

输入

String s1 = "This Payer Ref [customerRef] does not exist/This Card Ref [cardRef] has already been used."

我想删除所有带有[variable]的部分

输出

"This Payer Ref does not exist/This Card Ref has already been used."

你可以使用这个。

String s1 = "This Payer Ref [customerRef] does not exist/This Card Ref [cardRef] has already been used.";
s1=s1.replaceAll("\\[\\w+\\]", "");
System.out.println(s1);
