Java中如何获取uuid呢?

获取UUID的示例

//获取32位的uuid
String uuid=UUID.randomUUID().toString();
System.out.println(uuid);

//将获取到的uuid转换为大写
String uuidToUp=uuid.toUpperCase();
System.out.println(uuidToUp);

//将获取到的uuid去除"-"
String uuidreplace=uuid.replace("-", "");
System.out.println(uuidReplace);

//将去除"-"后的uuid转换为大写
String uuidRepToUp=uuidReplace.toUpperCase();
