Why do you not declare several variables of the same type on the same line?

Question

Why is it bad practice to declare variables on one line?

e.g.

private String var1, var2, var3

instead of:

private          


        

Answer 1

It is bad practice mostly when you can and want to initialize variables on the deceleration. An example where this might not be so bad is:

string a,b;
if (Foo())
{
  a = "Something";
  b = "Something else";
}
else
{
  a = "Some other thing";
  b = "Out of examples";
}
