publicclassIdGenerate{
publicstaticStringgetUUIDString(){
Stringid=UUID.randomUUID().toString();
id=id.replace("-","");
returnid;
}
publicstaticvoidmain(String[]args){
System.out.println(IdGenerate.getUUIDString());
}
}
importjava.util.UUID;
publicclassIdGenerate{
publicstaticStringgetUUIDString(){
Stringid=UUID.randomUUID().toString();
id=id.replace("-","");
returnid;
}
publicstaticvoidmain(String[]args){
