Write code to get the first Index Of a Char
//package com.book2s; public class Main { public static void main(String[] argv) { String sqlString = "book2s.com"; String string = "b"; int startindex = 4; System.out.println(firstIndexOfChar(sqlString, string, startindex)); }//from w w w.j av a2s.c o m public static int firstIndexOfChar(String sqlString, String string, int startindex) { int matchAt = -1; for (int i = 0; i < string.length(); i++) { int curMatch = sqlString.indexOf(string.charAt(i), startindex); if (curMatch >= 0) { if (matchAt == -1) { // first time we find match! matchAt = curMatch; } else { matchAt = Math.min(matchAt, curMatch); } } } return matchAt; } }
