如何用java替换字符串中的特定单词？

Question

我有这个字符串变量：

String a = "malam mingguan bareng geng motor kepominfo kemkominfo bem rema upi"; 

我想要做的就是取代“马拉姆mingguan”到“马拉姆-mingguan”。输出将如下：

String a = "malam-mingguan bareng geng motor kepominfo kemkominfo bem rema upi"; 

我该怎么做？

Answer 1

使用String.replace：

a = a.replace("malam mingguan", "malam-mingguan"); 

Answer 2

您可以使用replaceAll函数。

代码：

String a = "malam mingguan bareng geng motor kepominfo kemkominfo bem rema upi"; 
System.out.println(a.replaceAll("(?<=malam)\\s(?=mingguan)", "-")); 

输出：

malam-mingguan bareng geng motor kepominfo kemkominfo bem rema upi 

Answer 3

只需拨打replaceAll与像malam\s+mingguan正则表达式：

a.replaceAll("malam\\s+mingguan", "malam-mingguan");
