       System.out.println("LOGIN");
       System.out.print("Enter username:");
       userOne = sc.next();
        System.out.print("Enter password:");
        userOneP = sc.next();
 
              
        for(int i = 0; i<=length; i++){
            if(userOne.equals(username[i])){
                storeLog = i;
                break;

  }
 
  static void Checker(){
    if(userOne.equals(username[storeLog]) && userOneP.equals(password[storeLog])){
          System.out.println("Success");
          ChangePw();
      }else{
        System.out.println("Wrong!");
        Login();
      }
  }
 
  static void  ChangePw(){
  Scanner sc = new Scanner(System.in);
    System.out.print("Enter new Pin: ");
    password[storeLog]=sc.next();
    Login();

arrayindexoutofbounds kasi walang index 3 sa username. Index 0 to 2 lang
Solution: Change the "i<=length" to i<length

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

                storeLog = i;
