Search for Pattern using Java

Question

hello friends,
I am trying to read a 'C' file and trying to look for all the lines in the 'C' cod, wherever a function call has happened. How could I do that ??
Thanks

import java.io.*;
import java.util.Scanner;
import java.util.regex.Matcher;
import java.util.regex.*;
class FileParser{
    Scanner sc;
    FileParser(String fileName)throws FileNotFoundException{
     sc = new Scanner(new File(fileName));
    void getFunctions(){
     //sc.findInLine("([a-zA-Z]+) (\p{Punct})");
     sc.findInLine("");
     MatchResult result = sc.match();
     //for (int i=1; i<=result.groupCount(); i++)
        // System.out.println(result.group(i));//typo in API
     //System.out.println(result.group(1));
     //System.out.println(result.group(2));
    void getLoops(){
     //Search for patterns FOR, WHILE, DO-WHILE
     sc.findInLine("void");
     MatchResult result = sc.match();
     for (int i=0; i<=result.groupCount(); i++)
         System.out.println(result.group(i));
     /*     sc.findInLine("main");
     result = sc.match();
     for (int i=0; i<=result.groupCount(); i++)
         System.out.println(result.group(i));
     sc.findInLine("void");
     result = sc.match();
     for (int i=0; i<=result.groupCount(); i++)
         System.out.println(result.group(i));
    //Search for pattern FOR
    void getForLoops(){
    //Search for pattern WHILE
    void getWhileLoops(){
    //Search for pattern DO-WHILE
    void getDoWhileLoops(){
    //Search for Union
    //Search for Struct
}I have added/deleted stuff to try all the different combinations. This class basically will have methods to ....
1) Get a List of Function Calls with Line# in 'C' code
2) Get a List of Loops with Line# in 'C' code
import java.io.*;
class TestScan{
    public static void main(String[] args)throws IOException{
     FileParser fp = new FileParser("main.c");
     //     fp.getFunctions();
     fp.getLoops();
