Input:
1
1.2
A
If line1 is integer then I return
new Integer(1);
If line2 is float then I return
new Float(1.2);
What should return for line 3 being a character?
There is a character wrapper for char primitive type. You can do new Character(char input)
If you need to get an instance of java.lang.Character
from char
, you have two ways:
Character c = Character.valueOf('A');
Or:
Character c = new Character('A');
Both ways are equivalent except the first way is more efficient because it uses caching for ASCII characters: Character.valueOf('A') == Character.valueOf('A')
is always true.
If you need to convert String
to Character
, you can use the charAt
method:
Character c = "A".charAt(0);
boolean -->Boolean;char --->Character;byte -->Byte;short -->Short;int -->Integer;long -->Long;float -->Float;double -->Double; So new Character('A'); should be what you want
