Note the difference between matches() and find(), matches() return true if the whole string matches the given pattern. find() tries to find a substring that matches the pattern in a given input string. Also by using find() you don't have to add extra matching like - (?s).* at th...
FIND 'A' IN 'ABCD1234EFG' MATCH COUNT sy-tabix. WRITE: sy-tabix. Now if you want to find all alphabets in the string without using RegEx and by means of normal search pattern, you need a loop over all the 26 characters. Using RegEx, it would be easy to search and find all the ...
appendReplacementand#appendTail appendTailmethods can be used in tandem in order to collect the result into an existing string buffer or string builder. Alternatively, the more convenient#replaceAll replaceAllmethod can be used to create a string in which every matching subsequence in the input ...
