Can anyone explain what is homogeneous and heterogeneous ?

Question

I see one question says "What kind of data Arrays stores in Java ? homogeneous only or heterogeneous only ?" These words confuse me, what's the meaning of "homogeneous" and "heterogeneous" ? Can someone explain this point with examples ? And what are the main differences between homogeneous and heterogeneous ?

P.S. Answers can be applied to any kinds of languages.

Answer 1

"homo-" means same, "hetero-" means different.

In your case in particular they mean that a single Java array can only store one type, say, only numbers, or only strings.

In Javascript for example arrays are heterogeneous, because I can make an array that holds [5, "hello", new Object()], and in Java that's not possible.

Answer 2

Chemistry is too hard for me.

Answer 3

Homogeneous means the same type. Heterogeneous means diverse types. Arrays are homogeneous, since you declare the single type as part of the definition. Class data tends to be heterogeneous as you have integers, strings, other classes, etcetera.

Answer 4

wait!!!
today was my chemistry exam .
the mixture where the solute and solvent are divided equally is homogeneous
heterogeneous is vice versa

Answer 5

homogeneous means the same, heterogeneous means different

Answer 6

If a perticular set of objects belongs to same type then they are homogeneous else heterogeneous.

Answer 7

Chemie is boring

Answer 8

homo = home
home = similar members
