Java Scanner Tip: Consume Newline After Reading Numbers

💡 **Java Tip Learned Today!** While practicing Coding problems, I ran into a small but important issue: mixing numeric inputs (nextInt() / nextDouble()) with full-line strings (nextLine()) in Java. At first, my code was returning an empty string when I tried to read a sentence after numbers. 🙆♀️ The fix? Always consume the leftover newline after reading numbers: int i = scan.nextInt(); double d = scan.nextDouble(); scan.nextLine(); // consume leftover newline String s = scan.nextLine(); // now this works! ✅ Lesson learned: nextLine() reads until the newline character. If you don’t clear the leftover \n, it will give an empty string. Sharing this tip for anyone struggling with Scanner input issues in Java! 🚀 #Java #ProgrammingTips #LearnByDoing #Coding
