<line>My mistress' eyes are nothing like the sun,</line>
<line>Coral is far more red than her lips red.</line>
<line>If snow be white, why then her breasts are dun,</line>
<line>If hairs be wires, black wires grow on her head.</line>
<line>I have seen roses damasked, red and white,</line>
<line>But no such roses see I in her cheeks.</line>
<line>And in some perfumes is there more delight</line>
<line>Than in the breath that from my mistress reeks.</line>
<line>I love to hear her speak, yet well I know</line>
<line>That music hath a far more pleasing sound.</line>
<line>I grant I never saw a goddess go,</line>
<line>My mistress when she walks, treads on the ground.</line>
<line>And yet, by Heaven, I think my love as rare</line>
<line>As any she belied with false compare.</line>

ВОПРОС : что и самое главное где нужно нависать чтобы результат отображался не только в консоли командной строки но и В среде разработки.... А то лазить каждый раз в командную сторку не очень удобно
Спасибо!!!! |
