Buenas! sou novo na área de programação, e me deparei com um problema de um script pronto, mas não sei nem por onde começar, então se alguém poder me ajudar, ficaria grato... OBS.: Esse é o script original e está funcionando corretamente. package com.ximad.pvn.screens;

Apenas foi removido as seguintes linhas:

append("forth.");
append();
append(" Angry Birds!");
append();
append(" --- ");
append(" Angry Birds ");
append();
append(" Arkantoz ");
append();
append(" Version 2.0"); E não compila... se eu modifica com o Cavaj da erro na hora de executar o jogo e com o NetBeans nem chega a compilar, tentei também compilar com o javac pelo Prompt, da erro...
