জাভা + পেয়ারা 16 (পেয়ারা অতি প্রয়োজনীয় নয়, তবে কিছু জিনিস লিখতে একটু কম বিরক্ত করেছে)।
ঠিক আছে, আপনি কাজ করার কথা? কীভাবে এমন একটি প্রোগ্রাম সম্পর্কে যা প্রকৃত জাভা কোডটি লিখে, যা আসলে সংকলন করে (যদিও এটি বেশি কিছু করে না)।
অ্যানিমেশনটি দেখাতে অসুবিধা হয় তবে এই প্রোগ্রামটি একটি জাভা প্রোগ্রামটি ডিফল্ট অভিধান (250 সাধারণ ইংরেজি শব্দ) বা একটি নতুন লাইন বিস্মৃত ফাইল (কমান্ড লাইন আর্গুমেন্ট হিসাবে নেওয়া) ব্যবহার করে লিখে একটি বারে এটি একটি অক্ষরে কনসোলটিতে টাইপ করে মানুষের মনে হচ্ছে গতিতে । এটি নিজে চালানোর বিষয়টি নিশ্চিত করুন কারণ এই পোস্টটি ন্যায়বিচার করে না। এটি শেষ হয়ে গেলে এটি 1 মিনিট অপেক্ষা করে, তারপরে কনসোলে প্রচুর ফাঁকা লাইন প্রিন্ট করে এবং আবার শুরু হয় starts আমি বিভিন্ন পরামিতি যুক্তিসঙ্গতভাবে tweakable করতে এটি লিখতে চেষ্টা করেছি।
এছাড়াও, সাধারণত আমি এটিকে একাধিক ফাইলে রেখে দিতাম, তবে এটি চালানো আরও সহজ করার জন্য আমি সমস্ত ক্লাস এক সাথে ধাক্কা দিয়েছি।
