Java : assign a value in single row

Question

Im learning java from basics. One of the book they claimed int h = f = 10; will work but in real time its not working. Please explain.

My code:

int h = f = 10;

Why it is not working?

Answer 1

Try this :

int h, f;
h = f = 10;

but keep in mind, this will only work with immutable objects, like Integer or String. You cannot use the same for an object of a class because they would be pointing on the same instance and if you modify one, you'll modify the others !

Answer 2

We have to declare h and f first.

int a, b, c, d;

a= b = c = d = 10;

Answer 3

Because f is not declared yet. This will work:

int f, h;
h = f = 10;
