Revision cc794af1-b815-4a49-b39f-7c7fb5958129 - Stack Overflow

My string structure is following

characters 1-3 are uppercase alphabets including diacritics such Ň Ö Ï

Characters 4-7 will always be numbers.

8th is space

9th is forward slash 

10th space 

11th onwards are number.

 String str1 = "DIW785o / 42"; // expected result "DIW7850 / 42"
 String str2 = "QLR357Ï / 11"; // expected result "QLR3571 / 11"
 String str3 = "UÜÈ7477 / 00"; // expected result "UÜÈ7477 / 00"
 String str4 = "A / P8538 / 28"; // expected result "AÏP8538 / 00"
 String str5 = "CV0875Z / 01"; // expected result "CVO8752 / 01"
 String str6 = "SW / 2188 / 38"; // expected result "SWÏ2188 / 38"


I wanted replace first 3 characters such as

 replaceAll("[2]", "Z")
 .replaceAll("[0]", "O")
 .replaceAll("[5]", "S")
 .replaceAll(" // ","Ï) // replace space forward_slash space with Ï

and position where numbers with following
 

 .replaceAll("(?i)L|(?i)I", "1")
			.replaceAll("(?i)o", "0")
			.replaceAll("(?i)s", "5")
			.replaceAll("(?i)z", "2")
