Change font for \usepackage{listing}

Question

I have the following tex file :

\documentclass[12pt,a4paper,twoside]{report}
\usepackage{mathtools}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{listings}
\usepackage{color}
\definecolor{dkgreen}{rgb}{0,0.6,0}
\definecolor{gray}{rgb}{0.5,0.5,0.5}
\definecolor{mauve}{rgb}{0.58,0,0.82}
\lstset{
  language=Java,
  aboveskip=3mm,
  belowskip=3mm,
  showstringspaces=false,
  columns=flexible,
  ={\small\ttfamily},
  numbers=none,
  numberstyle=\tiny\color{gray},
  =\color{blue},
  commentstyle=\color{dkgreen},
  stringstyle=\color{mauve},
  breaklines=true,
  breakatwhitespace=true,
  tabsize=3
}
\begin{document}
\begin{lstlisting}[caption={Third median in terms of $\theta$ and $\phi$},label={lst:f4}]
p, t= var('p t') 
a=(-2*p*t^2-p^2*t)+(2*t*p-p^2)+t+1 
b=(p*t^2+2*p^2*t)+(2*t*p-t^2)-p+1 
c=(p*t^2-p^2*t)+(t^2+2*t*p+p^2)+t-p #3 sides (a,b,c) in terms of theta and phi
expand(2*a^2+2*b^2-c^2) #third median equation, m=1/2*sqrt(2*a^2+2*b^2-c^2)
        9*p^4*t^2 + 18*p^3*t^3 + 9*p^2*t^4 + 6*p^4*t + 18*p^3*t^2 - 18*p^2*t^3 -
         6*p*t^4 + p^4 - 22*p^3*t + 6*p^2*t^2 - 22*p*t^3 + t^4 + 2*p^3 - 6*p^2*t
         + 6*p*t^2 - 2*t^3 - 3*p^2 + 18*p*t - 3*t^2 - 4*p + 4*t + 4
\end{lstlisting}

\end{document}

I want to change the font of the listings to be smaller, probably \tiny. Can anyone guide me how to do it.

Hi Shahrina. I can't compile your source with Papeeria or Overleaf because there are many LaTeX Error, Undefined control sequence and others errors. — Sebastiano, Jan 23 '17 at 09:49
something is missing before ={\small\ttfamily} and =\color{blue}. You probably wanted to say basicstyle={\small\ttfamily}. If it's correct, replace \small by \tiny and you'll get an smaller typeface. — Ignasi, Jan 23 '17 at 10:21
@Ignasi Sorry, I didn't see your comment before I posted my answer, if you want to answer I can delete mine. — Torbjørn T., Jan 23 '17 at 10:24

The basicstyle key is probably what you're after, i.e.

\lstset{
basicstyle=\small\ttfamily,
...
}

\ttfamily is assuming you want to use the typewriter font. For smaller font than \small, replace \small with \footnotesize, \scriptsize or \tiny, depending on what you want.

There seems to be some keys missing from the key=value pairs in your lstset, you have ={\small\ttfamily} (which might be where you wanted basicstyle), and later =\color{blue}, though I don't what that was intended for, of course.
