Try this: import java.io.*; 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
"); 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("
" + search + " occurred " + total + " time(s)"); } }
