Java如何替換所有指定（出現）的字符串？

在Java編程中，如何替換所有指定(出現)的字符串？

以下示例演示如何使用Matcher類的replaceAll()方法替換字符串中的所有出現的子字符串。

package com.yiibai; import java.util.regex.Matcher; import java.util.regex.Pattern; public class ReplaceAllOccurrences { public static void main(String args[]) { Pattern p = Pattern.compile("Java"); String instring = "Java and Javascript all is the best languages."; System.out.println("initial String: " + instring); Matcher m = p.matcher(instring); String tmp = m.replaceAll("Python"); System.out.println("String after replacing 1st Match: " + tmp); } } 

Java

上述代碼示例將產生以下結果 -

initial String: Java and Javascript all is the best languages.
String after replacing 1st Match: Python and Pythonscript all is the best languages.
