Wrapper(==)-Q

[Vishnu Prakash]

 public class Test041
{ 
static double d;
static float f;
 
public static void main(String args[])
{ 
compare(Long.MAX_VALUE, Long.MAX_VALUE );
compare(Integer.MAX_VALUE, Integer.MAX_VALUE );
compare(Character.MAX_VALUE, Character.MAX_VALUE);
compare(Short.MAX_VALUE, Short.MAX_VALUE );
compare(Byte.MAX_VALUE, Byte.MAX_VALUE ); 
}
 
static void compare(double d, float f)
{
if (f == d) System.out.print(" equal" );
else System.out.print(" unequal"); 
} 
}
 
 

Q: Why Integer.MAX_VALUE is not returning unequal. The rest of things are
evaluating to equal

[ankur rathi]

Each statement should return 'equal' because everything ( long , int , char , short , byte ) can be cast into double & float without lossing precision .
