如何从字符串中删除第一个特殊字符

Question

I have values seperated by pipes in a database. But the issue is that I am appending | at every entry.

For Example:

|275634|374645|24354|

How can I remove the first pipe from the whole string not all the pipes.

Once inserted I don't need to check for the next time when it updates.

If I use substring(1) then it will remove the first character every time,

Please suggest a fix?

Answer 1

//input = '|275634|374645|24354|';
output = input.replace('|', '');

String#replace will replace the first occurance in a String. If you replace it with an empty String '' it is removed.

Answer 2

you can use substring(index) method where ever you want to remove the perticular special character from the String: like

String str2 = "|275634|374645|24354|";
 str2 = str2.substring(1);
System.out.println(str2);

you can see the output as 275634|374645|24354|
