我一直无法解决问题 [英] I have been unable to get a fix for a problem

问题描述

我无法解决问题。这是我的问题：



长位= 2

字符串替换= $ field2和$ field25

更换后= replacement.replace（$ field+ place，'1'）;

当我运行它时，它会单独替换$ field2并将$ field25中的$ field2替换为1.但我想要的确切要取代的话。我怎样才能用Java实现这个目标



测试程序将是最受欢迎的。



我试过这个词边界但它不起作用



我尝试过：



我尝试过单词边界但是当我使用$ field + variable时它没有用。当我只使用$ field时它被替换了，但目的没有解决。

I have been unable to get a fix for a problem . This is my problem:

long place = 2
String replaced = $field2 and $field25
afterreplacing= replaced.replace("$field" + place, '1');
When I run this it is replacing $field2 alone and also $field2 in $field25 by 1. But I want the exact word to get replaced . How can I achieve this in Java

Tested programs will be most preferred.

I tried the word boundaries but it didn't work

What I have tried:

I tried the word boundaries but it didn't work when I used $field + variable . It was getting replaced when I was using just "$field" but the purpose is not resolved.

推荐答案

field2和

field25

afterreplacing = replacement.replace（

field25
afterreplacing= replaced.replace("

field+ place，'1'）;

当我运行它时正在取代

field" + place, '1');
When I run this it is replacing
