<p>কোডে কোন ভুল ইনপুট এলে তোমার কোড ঠিক মতো কাজ করতে পারবে না। যেমন একটা মেথডের প্যারামিটার হিসেবে যে ডাটা দিলে তোমার কোড কাজ করবে, যদি ভুলবশত অন্য ডাটা দেয়া হয় তখন প্রোগ্রাম কাজ করতে পারবে না। এটাকে বলে exception। জাভাতে এই exception গুলো হ্যান্ডল করার জন্য পদ্ধতি আছে। আমরা পরের আপডেটে এটি নিয়ে আলোচনা করবো।</p>
