Binary Search in Java | Dry Run, Logic & Code (ICSE Class 10)

Binary Search in Java explained step by step with manual dry runs, clear logic, and full code—perfect for ICSE Class 10 students and Java beginners. In this video, you’ll clearly understand how binary search works on a sorted 1D array, including both successful and unsuccessful searches. If you already know linear search and want to move to faster searching techniques, this lesson will help you master the binary search algorithm in Java with zero confusion. This video on binary search in Java for ICSE Class 10 is designed to build strong programming logic from the basics. We start by recalling linear search and explaining what a sorted array means—a key requirement for binary search. Then, we move into the definition of binary search, followed by the three cases of binary search used in exams. You’ll see a binary search dry run in Java on two arrays, covering both successful and unsuccessful search cases. Special focus is given to the low, mid, and high concept, which is one of the most confusing parts for beginners. Every step is explained using an algorithm dry run technique, exactly how ICSE expects answers. Later in the video, we derive the binary search logic for ascending order and descending order, and finally implement the binary search program in Java with clean, exam-oriented code. This makes the video ideal for ICSE computer applications, Java array searching, and exam-oriented Java programs. Whether you are learning Java programming, revising data structures basics, or preparing for ICSE algorithm questions, this lesson will strengthen your problem-solving techniques and logical thinking.
