如何删除字符串中的每一个第2个字符？ [英] How to delete every 2nd character in a string?

问题描述

如何删除字符串中的每一个第2个字符？

例如：

  3030313535333635  - ＆GT; 0015536​​5
3030303336313435  - ＆GT; 00036145
3032323437353530  - ＆GT; 02247550
 

中的字符串始终是16个字符长，结果总是8个字符 - 这是要删除的角色始终是一个'3' - 不要问为什么但是 - 我做梦也没想到了这个疯狂的源数据

解决方案

 字符串输入=3030313535333635;
字符串结果=;
的for（int i = 1; I＆LT; 16; I + = 2）
{
    结果+ =输入[I]
}
 

How to delete every 2nd character in a string?

For example:

3030313535333635  -> 00155365
3030303336313435  -> 00036145
3032323437353530  -> 02247550

The strings are always 16-characters long and the result is always 8 characters long - and the character that is being removed is always a '3' - Don't ask why however - I did not dream up this crazy source data.

解决方案

String input = "3030313535333635";
String result = "";
for(int i = 1; i < 16; i +=2 )
{
    result += input[i];
}
