I want to compare charArray and char I keeps character in charArray such as: char[] charArray = {'J','N','E'} and get input from keyboard each character keeps in variable charInput This code below check character by character and no run on index CODE public static int Check(char[] charArray , char inputChar){ for(int index = 0;index<charArray.length;index++){ if(charArray[index] == inputChar){ index++; System.out.println("equals"); } } return index; } If I want to specify first index for check is index[0] and then if index[0] are equal let check next index (index [1],... until last index) How to solve this problem? Thanks.

Thanks. Don't really understand what you mean. But let's guess: - You do not have to increment index if it is found, you have your answer - your code cannot compile because index is not defined outside the loop java public static int Check(char[] charArray , char inputChar){ for(int index = 0; index<charArray.length; index++){ if(charArray[index] == inputChar){ System.out.println("equals at index: " + index); return index; } } // not found return -1; } This post has been edited by pbl: 4 Apr, 2008 - 10:25 AM
