How to get a specified value from string

Hi,

I have below values in a string

String s1 = ' __valuesE-123456yes__'
String s2 = '__values2E-234567fail__'

I need to fetch only the values starting from 'E- to the next 6 digit values from the strings
Ouptut should be like : E-123456
E-234567

Can you please let me know how to achieve this?

Thanks

Hi Monishan,
Use the substring(startIndex, endIndex), stating the start index and the end index.

For String s1 = ' __valuesE-123456yes__'; 
System.debug('Result: '+ s1.substring(8, 16));

!) There is a space between the apporstrophe and the first underscore. So I deleted it. That is why the starting index is 8 and the end index is 16. If you don't want ot delete the white space, then the starting index will be 9
2) I executed the snippet on Anonymous window and got the result below:
    USER_DEBUG [2]|DEBUG|Result: E-123456
3) Use the same method for the second one.
For more information, go to:

Please, let me know if this helps you

Hi Monishan,

If you've some specific string formats like this, and looking to get the sub string starting with "E-", it'll be better to first find the index of "E-" in the original string and then get the required substring starting from that index.

Here is a working code for example: 
String s1 = '__valuesE-123456yes__';
String s2 = '__values2E-234567fail__';

Integer index1 = s1.indexOf('E-');
Integer index2 = s2.indexOf('E-');
System.debug(s1.substring(index1, index1+8));
System.debug(s2.substring(index2, index2+8));
