    Default Comparing a character with characters within a string

    When I run the applet that uses this piece of code I get the following error:
    ALERT: java/lang/ClassFormatError: Bad version information.

    public void checkInput()
    char gletter = 'x';
    String sword;

    //split String into stringArray
    char[] stringArray;
    stringArray = sword.toCharArray();


    //set receiver

    //compare chars
    byte[] swordBytes = sword.getBytes();

    for(int i = 0; i < sword.length; i++)
    if(i < swordBytes.length)
    if(byte[i] swordBytes comparesTo gletter) <---byte gives a syntax error (I really don't know what I actually have to put here, I've tried multiple things like string and char. swordBytes gives a 'cannot be resolved to a type' error. [i] gives an error saying I need to place a ")".
    frame[i+14] = gletter;

    //send frame

    If someone could explain what I am doing wrong, it would be highly appreciated.

    Try some System.out.println() statements in your for-loop to see what is stored in your variables.

    When I was starting out, here is what I used MANY TIMES to troubleshoot array and loop issues :

    for(int i=0;i<var.length;i++){

    I hope this helps!
