如何使用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";

我想做的是取代＆＃34; malam mingguan＆＃34;到了＆＃34; malam-mingguan＆＃34;。输出将是这样的：

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

只需使用replaceAll

等正则表达式调用malam\s+mingguan即可

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