In the Wild West of text manipulation, Groovy offers two gunslingers for splitting strings: tokenize()<\/strong> and split()<\/strong>. They might seem like two sides of the same coin, but choosing the right one can make your code smoother than a well-oiled six-shooter.<\/p>\n

Below are some of the significant differences between both tokenize()<\/strong> and split()<\/strong><\/p>\n\n\n\n\n\n\n\n
Feature\u00a0<\/strong><\/td>\ntokenize()\u00a0<\/strong><\/td>\nsplit()<\/strong><\/td>\n<\/tr>\n
Return Type<\/td>\nList<\/td>\nString[]<\/td>\n<\/tr>\n
Handles Empty Strings<\/td>\nIgnores empty tokens<\/td>\nIncludes empty tokens<\/td>\n<\/tr>\n
Supports Regex Delimiters<\/td>\nNo<\/td>\nYes<\/td>\n<\/tr>\n
Multi-character Delimiters<\/td>\nEach character treated as a delimiter<\/td>\nFull string used as delimiter<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

  1. Both methods split a string into tokens but with subtle nuances. The split() method returns a string [] instance, while the tokenize() method returns a list instance.<\/li>\n
  2. \u00a0tokenize(), which returns a list, will ignore an empty string (when a delimiter appears twice in succession), whereas split() keeps such string.\n
    [java]\r\nString testString = 'hello brother'\r\nassert testString.split() instanceof String[]\r\nassert ['hello','brother']==testString.split() \/\/split with no arguments\r\nassert['he','','o brother']==testString.split('l')\r\n\/\/ split keeps empty string\r\nassert testString.tokenize() instanceof List\r\nassert ['hello','brother']==testString.tokenize() \/\/tokenize with no arguments\r\nassert ['he','o brother']==testString.tokenize('l')\r\n\/\/tokenize ignore empty string\r\n[\/java]<\/pre>\n<\/li>\n
  3. The tokenize() method uses each character of a String as a delimiter whereas split()\u00a0 takes the entire string as a delimiter\n
    [java]\r\nString testString='hello world'\r\nassert ['hel',' world']==testString.split('lo')\r\nassert ['he',' w','r','d']==testString.tokenize('lo')\r\n[\/java]<\/pre>\n<\/li>\n
  4. The split() can take regex as a delimiter whereas tokenize does not.\n
    [java]\r\nString testString='hello world 123 herload'\r\nassert['hello world ',' herload']==testString.split(\/\\d{3}\/)\r\n[\/java]<\/pre>\n
    So, next time you need to split strings in Groovy, remember these gunslingers. Choose the one that fits your task and shoot down those stringy dilemmas with ease!<\/p>\n
