Expand Post »

java Syntax (Toggle Plain Text)
class WrapperTest
{
	public static void main(String[] args){
		Byte b = new Byte(3);
		Short s = new Short(34);
	}
}
class WrapperTest
{
	public static void main(String[] args){
		Byte b = new Byte(3);
		Short s = new Short(34);
	}
}

when I try to compile this is the problem I got

Java Syntax (Toggle Plain Text)
G:\WORK PLACE\work>javac WrapperTest.java
WrapperTest.java:4: cannot find symbol
symbol  : constructor Byte(int)
location: class java.lang.Byte
                Byte b = new Byte(4);
                         ^
WrapperTest.java:5: cannot find symbol

location: class java.lang.Short
                Short s = new Short(34);
                          ^

Re: what is the wrong with Byte constructor which takes int value

Probably because there isn't such constructor.
API for Byte object
API for Short object
The values in the parenthesis are not treated as byte and short but as int. I haven't try this and I don't know if it will work so don't blame me, but try:
Byte b = new Byte( (byte)3 );
Short s = new Short( (short)34 );

Actually it works

if we do like this.

Byte b = 3;
Short s = 34;
