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.)

May 16, 2023JDK 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

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.

Deprecated. It is rarely appropriate to use this constructor. Use parseInt(String) to convert a string to a int primitive, or use valueOf(String) to convert a string to an Integer object. Constructs a newly allocated Integer object that represents the int value indicated by the String parameter.
