You can use
Integer integer = Integer.valueOf(i);
From the javadoc of the constructor:
Deprecated. It is rarely appropriate to use this constructor. The static factory valueOf(int) is generally a better choice, as it is likely to yield significantly better space and time performance. Constructs a newly allocated Integer object that represents the specified int value.
The main difference is that you won't always get a new instance with valueOf as small Integer instances are cached.
All of the primitive wrapper types (Boolean, Byte, Char, Short, Integer, Long, Float and Double) have adopted the same pattern. In general, replace:
new <WrapperType>(<primitiveType>)
with
<WrapperType>.valueOf(<primitiveType>)
(Note that the caching behavior mentioned above differs with the type and the Java platform, but the Java 9+ deprecation applies notwithstanding these differences.)

Should I replace a statement with a deprecated constructor? (Java in General forum at Coderanch)
June 28, 2023 - Yes, at some point you should replace Vector with List. You can add an int to a List<Integer>. In general, whenever an assignment context expects a wrapper type such as Integer, you can assign a primitive type (such as int) directly to it. Java will automatically convert the int to an Integer.
JDK 9 deprecates Number constructors, e.g. Integer(int)
I believe this isn't new, and has been going on for the last few versions at least. Industry-wide APIs are using more static code over the more Object-oriented ( Or "Instance" oriented? ) approach of the last decades. Constructors in general are used less, and static factory functions are used more. I've been doing this myself, using an "Immutable by default" approach to objects; "final" classes with all final members and with private constructors only but static factory methods. It seems that is tied to moving to a more Functional approach to languages and APIs. As higher concurrency requirements are causing this approach to look more attractive every day. More on reddit.com

No longer deprecate wrapper class constructors for removal
April 10, 2025 - The constructors of primitive wrapper classes like Integer have been deprecated since Java 9, because they force the creation of wrapper objects with new identities, and it has long been discouraged to depend on the identity of a wrapper object.

Replace Inefficient Constructors with valueOf() | jSparrow Documentation
For example new Integer("1") becomes Integer.valueOf("1"). Using this rule saves memory and CPU cycles, as the constructors are not needed in this case. Furthermore, the constructors are deprecated in Java 9, which is an indication that they will eventually be removed from the language altogether.
