public class IdGenerate {

public static String getUUIDString() {

String id = UUID.randomUUID().toString();

id = id.replace("-", "");

return id;

}

public static void main(String[] args) {

System.out.println(IdGenerate.getUUIDString());

}

}

import java.util.UUID;

public class IdGenerate {

public static String getUUIDString() {

String id = UUID.randomUUID().toString();

id = id.replace("-", "");

return id;

}

public static void main(String[] args) {

System.out.println(IdGenerate.getUUIDString());

}
