So basically I want to create a Table of Contents in my latex document (class - article). But I don't want the first half sections to be printed. For examples, suppose there are four sections in my document - Section 1, Section 2, Section 3 and Section 4. Then I want my TOC to look like this

1. Section 3 -- pagenumber

2. Section 4 -- pagenumber

While I want to retain the section number and names in the main text.

Thanks!

Welcome to TeX.SX. Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – Christian Hupfer Jul 28 '14 at 21:56
\section*{First section} etc should do for not appearing in the TOC. – Christian Hupfer Jul 28 '14 at 21:57

Depending on the request, there are some possibilities:

\section*{Title} ---> No toc entry at all

\section[]{Title} ----> No toc entry, but numbered section

\documentclass[paper=a4,12pt]{scrartcl}

\usepackage{blindtext}

\begin{document}
\tableofcontents
\clearpage

\section*{First -- not in TOC}%
\blindtext
\section*{Second -- not in TOC too}%
\blindtext
\section{Third}%
\blindtext
\section{Fourth}%
\blindtext
\section[]{Fifth}%
\blindtext
\end{document}

This answer works with the "scrartcl" class, but not (for me) with the "article" or "amsart" classes. With "article", \section* is left out of the TOC while \section[] inserts a blank but numbered line into the TOC, while with "amsart" all three commands add TOC entries (with \section* being an unnumbered entry and the other two numbered). – Mike Shulman Sep 23 '15 at 4:22
@MikeShulman: Yes? What's your addition to this? – Christian Hupfer Sep 23 '15 at 12:02
I don't understand your question. I was pointing out that your answer only works with a particular document class (which happens not to be the one the OP said he was using). – Mike Shulman Sep 23 '15 at 23:12
@MikeShulman: I never claimed it would work with other classes – Christian Hupfer Sep 24 '15 at 8:11
Sure. But since you didn't actually mention document classes at all, I spent a while being confused about why your solution didn't work for me, until I realized it depended on the document class. So I thought I would spare other readers that wasted time. – Mike Shulman Sep 24 '15 at 13:36
