Hello...Java is supporting mutiple datatypes declarations in for loop

is it possible to declare more than one data types in a for loop...i think java is supporting multiple declarations in for loop..am i right
class check
     public static void main(String[] args)
          for(int i=10,float k=10;i<5;i++)
               System.out.println("Hello World!"+i);

Hi,
no, that doesn't work because java unlike c++ does not
have the comma operator ",". So you need to declare
the 2nd variable in the body of the loopNot strictly correct - its true that it won't work in this case, but false that Java doesn't recognise the comma.
If your two variables were of the same type you could use something like
for (int i = 0, k = 10; i < k; i++)
However, the initialisation must take place in a single statement, so you can't use multiple types
