Did a Java tech interview today

[Garet Jax]

Asked him to name the 8 primitive data types:

he named:

byte
int
double
big int
big double
string
boolean
char

😕

 

[BigJ]

5/8 not good enough for ya? 😉

 

[Terabyte]

byte short int long float double char boolean

What do I win? 🙂

 

[tfinch2]

short
long
float
double
byte
int
char
boolean

 

[Garet Jax]

It's not that he didn't know all 8, as much as it's that he said String was one of them.

Very, especially since he did say char.

What's also suprising is that he didn't say float. I could see forgetting about short and long, but not float.

he actually said character, but I game him the benefit of the doubt 🙂

What is a long, short and double? I understand the others from college when I was studying programming in Turbo Pascal.

Ahh, lol, I probably covered this whilst studying Pascal but I can?t remember it. It was a long time ago.

Anyway, I understand now, thanks. 🙂

I'm more surprised by the big int & big float than the others... I mean strings are primitive in some languages. But if you have a need for "arbitrary" precision numbers, it seems like you really ought to know something about them... like how you would have to include the BigInteger and/or BigDecimal classes...

byte - 8 bit integral
short - 16 bit integral
int - 32 bit integral
long - 64 bit integral
float - 32 bit decimal
double - 64 bit decimal

Latte?

 

[WobbleWobble]

I probably would have said String as well, oops.

 

[aceO07]

I'm just curious, what other questions did you ask? What were you trying to learn from the questions?

That?s a good break down. 🙂
