Write code to strip string End.
abc becomes ab
Use while statement to check the ends.
//package com.book2s; public class Main { public static void main(String[] argv) { String str = "book2s.com"; String stripChars = "com"; System.out.println(stripEnd(str, stripChars)); }//w ww .j a v a 2s. c o m public static final int INDEX_NOT_FOUND = -1; public static String stripEnd(String str, String stripChars) { int end; if (str == null || (end = str.length()) == 0) { return str; } if (stripChars == null) { while ((end != 0) && Character.isWhitespace(str.charAt(end - 1))) { end--; } } else if (stripChars.length() == 0) { return str; } else { while ((end != 0) && (stripChars.indexOf(str.charAt(end - 1)) != INDEX_NOT_FOUND)) { end--; } } return str.substring(0, end); } }
