cast double to byte

[karang]

Hi

If some one asked me in an interview - Can we cast double value to byte. For that I have compiled an answer

Yes. Consider the example below

class MainClass
{
public static void main(String aa[])
{
double d=22.55;
byte b=(byte)d;
System.out.println(b);
}
}

Output
22

.55 will be lost

Is this answer fine?

You haven't bothered to reply to the two responses on your earlier thread. Not the best way to continue to get help on a forum, that.

Also, go through BB Code List - Java Programming Forum and edit your post accordingly.

Yes, but if the double value bigger than the max value of a byte (+127) or smaller than the min value of a byte (-128) you will get an overflow!

		double d= -129;
		byte b=(byte)d;
		System.out.println(b);	
		
		d= 128;
		b=(byte)d;
		System.out.println(b);
