We Are Going To Discuss About The constructors Integer(int), Double(double), Long(long) and so on are deprecated. So lets Start this Java Article.
The constructors Integer(int), Double(double), Long(long) and so on are deprecated
- The constructors Integer(int), Double(double), Long(long) and so on are deprecated
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 constructors Integer(int), Double(double), Long(long) and so on are deprecated

Solution 1
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.)
