    Don't try to get a character from a String at position -1.

    kind regards,

    Please Check this code

    findIf = lineOfFile.indexOf("if");
    findWhile = lineOfFile.indexOf("while");
    findElse = lineOfFile.indexOf("else");
    //For if and While
    for(i=0 ; i<2; i++)
    {
    if(i==1)
    findIf = findWhile;
    //If 'if' is found, check to see if 'if' is a an if statement
    if (findIf != -1) {
    precedingChar = lineOfFile.charAt(findIf - 1);
