Given

code
-------------------------
Float f2=new Float(3.14f);
System.out.println("byte="+f2.byteValue());
System.out.println("short="+f2.shortValue());
System.out.println("intt="+f2.intValue());
System.out.println("long "+f2.longValue());
}

code
----------------------------------
wat is the criteria for getting the value getting truncated to 3
All except

1)System.out.println("double "+f2.doubleValue());
2)System.out.println("float "+f2.floatValue());

truncates the value to 3
I expect f2.longValue also to behave differently rather than printing 3

byte, short, int, and long are all "integral types", meaning they can only represent integers -- numbers with no fractional parts. None of those types can hold 3.14, but they can hold 3. float and double are "floating point types", and they can represent numbers with fractional parts.
