Try this:

import java.util.*;

public class CountChar

{

public static void main (String[]args) throws Exception

{

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

System.out.println("Enter several lines of text or a blank line to finish\n");

List list = new ArrayList();

String line;

while(true)

{

line = br.readLine();

if (line.length() == 0) break;

list.add(line);

}

System.out.print("Enter search character : ");

String input = br.readLine();

char search = input.charAt(0);

br.close();

int total = 0;

for(String s : list )

{

int index = 0;

while((index = s.indexOf(search, index)) > -1)

{

total++;

index++;

if (index >= s.length()) break;

}

System.out.println("\n" + search + " occurred " + total + " time(s)");

}
