在Java中删除部分字符串 [英] Remove part of string in Java

问题描述

我想从一个字符中删除一部分字符串，即：

I want to remove a part of string from one character, that is:

源字符串：

manchester united (with nice players)

目标字符串：

manchester united

推荐答案

有多种方法可以做到这一点。如果您有要替换的字符串，则可以使用替换或替换所有 <$ c $的方法c> String class。如果您要替换子字符串，可以使用 substring API获取子字符串。

There are multiple ways to do it. If you have the string which you want to replace you can use the replace or replaceAll methods of the String class. If you are looking to replace a substring you can get the substring using the substring API.

例如

String str = "manchester united (with nice players)";
System.out.println(str.replace("(with nice players)", ""));
int index = str.indexOf("(");
System.out.println(str.substring(0, index));

要替换（）中的内容，您可以使用：

To replace content within "()" you can use:

int startIndex = str.indexOf("(");
int endIndex = str.indexOf(")");
String replacement = "I AM JUST A REPLACEMENT";
String toBeReplaced = str.substring(startIndex + 1, endIndex);
System.out.println(str.replace(toBeReplaced, replacement));
