如何用java替換字符串中的特定單詞？

Question

我有這個字符串變量：

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

我想要做的就是取代「馬拉姆mingguan」到「馬拉姆-mingguan」。輸出將如下：

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

我該怎麼做？

Answer 1

使用String.replace：

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

Answer 2

您可以使用replaceAll函數。

代碼：

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

輸出：

malam-mingguan bareng geng motor kepominfo kemkominfo bem rema upi 

Answer 3

只需撥打replaceAll與像malam\s+mingguan正則表達式：

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