Question

I have one String = GETMSG_m_m_5556 from this I want to read only 5556, means I want to read all the digits after last “_”. The string has not fixed length of numbers it may be like, GETMSG_m_m_9898786589 OR GETMSG_m_m_98987865. So how can I read the numbers after “_”?

Can anyone suggest me the write way.? It may be foolish question but I am stuck on this. I cant get any idea about this.

Thanks in advance.

String digits = sampleString.subString(sampleString.lastIndexOf("_"),sampleString.lenght);

Get the last index of the char ‘_’ in your string and make a required substring to get the numbers .see string.subString()
