Hi everyone ! I am a Java beginner and I had practice Python before. Recently, I started my Java lesson in my school . Once, teacher ask us to type in the code on the paper she gave into the computer and run it. But when I tested, I saw that there are a lot of errors in that printed worksheet paper ( Like [] , on the paper it is a rectangal). Luckily, it is solved. Now , I decide to start to learning Java by myself . So, I need your help for Java. Thank You !!! ( From a 16 years old secondary school students in Malaysia
