passing a float to a double

[Christie George]

hi,
my issue is like this..

i have a float variable,is it possible for me to pass this (float) variable to a method thats taking a double as arguement? i am not applying any cast to the float variable.

Yes !
Since double is a bigger container, it can hold float values (which would fit in it). Explicit casting is not required.

public class FloatDouble
{
public static void main(String args[])
{
float f = 5f;
Print(f);
}
 
public static void Print(double d)
{
System.out.println(d);
}
}

ok fine agreed...but in such a case will the extra bits of the float value be filled with a junk value(when its passed)?

Nope !!!
