which one to use first between this and super?

[Sonu Nigam]

if in a subclass we want superclass constructor to be accessed and i want to use both this and super keyword and both are written just after the constructor defined then in above case which one will be written first?

You can't call both a super- and this-constructor in one constructor. It's simply not allowed.

[Ernest Friedman-Hill]

You can only use one of the two. If you use "this", then another constructor will be called in the same class; if that constructor uses "this", then a third constructor will be called, etc. Eventually, you'll get to a constructor that doesn't use "this", and in that constructor, "super" can appear.
