Reports any attempt to instantiate a new Long
,
Integer
, Short
, or
Byte
object from a primitive long
,
integer
, short
, or
byte
argument.
It is recommended that you use the static method valueOf()
introduced in Java 5. By default, this method caches objects for values between -128 and
127 inclusive.
Example:
Integer i = new Integer(1);
Long l = new Long(1L);
After the quick-fix is applied, the code changes to:
Integer i = Integer.valueOf(1);
Long l = Long.valueOf(1L);
This inspection reports if the language level of the project or module is 5 or higher
Use the Ignore new number expressions with a String argument option to ignore calls to number constructors with a String
argument.
Use the Report only when constructor is @Deprecated option to only report calls to deprecated constructors.
Long
, Integer
, Short
and Byte
constructors are deprecated since JDK 9.
