برنامج معالجة النصوص بجافا

السلام عليكم و صح فطوركم

أضع بين أيديكم برنامج مطور بلغة جافا مشابه لبرنامج مفكرة ويندوز

فمن منطلق التعاون بين مبرمجين العرب على دعم برمجيات الحرة

فقمت بصناعة برنامج يعالج النصوص البسيطة

فقد إستغرق لي هذا البرنامج حولي أسبوع من التطوير

فأرجو من أصحاب الخبرة في جافا ان يقيمو هذا البرنامج لأني مبتدئ في عالم جافا

موصفات البرنامج

فتح ملف نصي

حفظ ملف نصي

طباعة ملف نصي

بحث في وسط ملف نصي

و إضافة الوان و تغير حجم خط النص

و عمليات بيسطة كالقص و لصق و نسخ و......
