Generating a UUID in Java is extremely easy. In fact, it can be done with a single line of code! To generate a type 4 UUID in Java, simply run the following line of code.<\/p>\n
\r\nString uuid = UUID.randomUUID().toString();\r\n\r\n\/\/ Example: e03913fb-5951-4964-a88b-47371641fd17\r\n<\/pre>\nBecause you will likely generate UUIDs in many different contexts, here is a handy helper utility for you.<\/p>\n
\r\npublic final class GeneralUtils {\r\n private GeneralUtils() { }\r\n\r\n public static String generateUUID() {\r\n return UUID.randomUUID().toString();\r\n }\r\n}\r\n<\/pre>\nIt can then be used as follows.<\/p>\n
\r\nString uuid = GeneralUtils.generateUUID();\r\n<\/pre>\nNot a huge difference, but I personally find the last line easier to remember. Plus, as long as I remember where my UUID method resides, intelli sense will guide me the rest of the way.<\/p>\n
I hope this helps.<\/p>\n","protected":false},"excerpt":{"rendered":"
