In order to add some fun to the process of learning Java! I will occasionally write some interesting programs and share them with you. If there are any errors or improvements in the code, please correct me.
Meet is [Apefen] If you have a more interesting program, please share it in the comment area, thank you very much!
Don't talk nonsense about GO! GO! GO!
- Formula to generate random integer
(int)(Math.random()*(b-a+1) + a);
- Generate random number: [1,100]
int random = (int)(Math.random()*100 + 1);
After knowing how to generate random integers, then we can add some judgments and loop statements to solve the Java number guessing game:
