In java what does this mean? int x = y, z;

Question

Seems like a very silly question, but i am unable to find an answer on this online.

basically what i am confused about is what does this code mean:

int x = y , z;

Why x has two values, separated by comma?

Answer 1

It's the same like :

int x = y;
int z;

Answer 2

x没有两个值，它具有y值，并且还有另一个int变量z 。

Answer 3

Those are two separate statements.The first expression x= y is an assignment operation. It assigns the value y to x. The second statement is initialization of z. For this to work, the value y should have been initialized before.
