1. I checked all imports they are correct the only error I am getting is while calling the List.of() method.

UserDao user1 = new UserDao();
user1.setName("j");
user1.setUser_name("k");
user1.setPassword("l");
user1.setPhone("86632");
    
UserDao user2 = new UserDao();
user1.setName("j");
user1.setUser_name("k");
user1.setPassword("l");
user1.setPhone("86632");

2. Here the of method is not found in spring tool suite I am on jre1.8

List<UserDao> users = List.of(user1, user2);
Iterable<UserDao> itrb = userRepo.saveAll(users);

CodePudding user response：

List.of is introduced starting from Java 9. So that you have to upgrade your Java to make use of one.

CodePudding user response：

You need atleast Java 9 for using List.of() function https://docs.oracle.com/javase/9/docs/api/java/util/List.html#immutable

CodePudding user response：

You should upgrade to Java9 to use List.of function, or use Arrays.asList instead.
