逐个替换字符串中的重复单词

Question

你好像下面的字符串

String str =＆＃34; vishwa sgsu shishs sjishs vishwa sjsjos vishwa＆＃34 ;;

我必须替换下面的每个事件

1. vishwa with xyz
2. vishwa with yzk
3. vishwa with jey

所以我的结果字符串将如下所示

＆＃34; xyz sgsu shishs sjishs yzk sjsjos jey＆＃34;

我尝试使用replaceFirst（），replace（）方法，但没有工作。

我该怎么做？？

Answer 1

如果您需要更强大的功能，请使用此功能 -

String original = "vishwa sgsu shishs sjishs vishwa sjsjos vishwa";
String s = "vishwa";
String [] replacements = { "xyz", "yzk", "jey" };
for (int i = 0; i < replacements.length; i++) {
    if (original.contains(s)) {
        original = original.replaceFirst(s, replacements[i]);
    } else {
          break;
    }
}
System.out.println(original);

如果你需要替换更多字符串，循环就可以完成工作。

Answer 2

请使用以下代码并检查您的输出。

  String str = "vishwa sgsu shishs sjishs vishwa sjsjos vishwa";

  String strNewString = str.replace("vishwa","xyz");
  strNewString = strNewString.replace("vishwa","yzk");
  strNewString = strNewString.replace("vishwa","jey");

现在使用strNewString作为将来使用。

Answer 3

试试

String someString = "vishwa sgsu shishs sjishs vishwa sjsjos vishwa";   
someString = someString.replaceFirst("vishwa","xyz");
someString = someString.replaceFirst("vishwa","yzk");
someString = someString.replaceFirst("vishwa","jey");

Answer 4

由于replaceFirst创建了一个新字符串，你可以通过

来完成

String result = str.replaceFirst("vishwa", "xyz") .replaceFirst("vishwa", "yzk") .replaceFirst("vishwa", "jey")
