這是代碼來說明java.lang.NoClassDefFoundError。有關詳細說明，請參閱Jared的答案。

NoClassDefFoundErrorDemo.javapublic?class?NoClassDefFoundErrorDemo?{

public?static?void?main(String[]?args)?{

try?{

//?The?following?line?would?throw?ExceptionInInitializerError

SimpleCalculator?calculator1?=?new?SimpleCalculator();

}?catch?(Throwable?t)?{

System.out.println(t);

}

//?The?following?line?would?cause?NoClassDefFoundError

SimpleCalculator?calculator2?=?new?SimpleCalculator();

}}

SimpleCalculator.javapublic?class?SimpleCalculator?{

static?int?undefined?=?1?/?0;}
