Efficient method to generate uuid string in java uuid randomuuid tostring without the dashes

Question

I want to generate random strings in an efficient way for alphanumeric characters without dashes or special symbols. I tried UUID.randomUUID().toString(), but it generates the string with dash like this 44e128a5-ac7a-4c9a-be4c-224b6bf81b20. 

Can anyone tell me how to do it?

Check the below code:

public static void main(String[] args) {

    final String uuid = UUID.randomUUID().toString().replace("-", "");

    System.out.println("uuid = " + uuid);

}
