In my Java class i am declaring variable like this
BigDecimal sumFeeBilled = new BigDecimal(0), sumPaid = new BigDecimal(0);
Or we have to declare like this in multiple line
BigDecimal sumFeeBilled = new BigDecimal(0);
BigDecimal sumPaid = new BigDecimal(0);
Which one we should follow ?

To declare (create) a variable, you will specify the type, leave at least one space, then the name for the variable and end the line with a semicolon ( ; ). Java uses the keyword int for integer, double for a floating point number (a double precision number), and boolean for a Boolean value (true or false).
Declaring each variable on a separate line is the preferred method. However, multiple variables on one line are acceptable when they are trivial temporary variables such as array indices.
int a, b, c; You can also assign multiple variables to one value: a = b = c = 5; This code will set c to 5 and then set b to the value of c and finally a to the value of b .
The less things that happen on a single line the better. If you choose the second option the code will be easier to debug(you can put a breakpoint on the line where the second initialization happens skipping the first one for instance) and easier to read(IMHO). The only thing that this costs you is a single line. I think it is worth it.
