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 - The reason for using Integer is the value is added to a vector for some bookkeeping (at some point the vector's contains method is called) so I guess the parameter must be an object. Perhaps using a vector is not the best of options and a list would be more appropriate, but first I'll study this working code and eventually I'll make my modifications. ... 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.

No longer deprecate wrapper class constructors for removal
April 10, 2025 - Revert them to simply "deprecated". 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.
