Download math-game.jar and start with the java -jar command:

wget https://arthas.aliyun.com/math-game.jar java -jar math-game.jar{{execute T1}}

math-game is a very simple program that randomly generates integers, performs factorization, and prints the results. If the generated random number is negative, a error message will be printed.

To make a contrast with using vmoption afterwards, now we use Ctrl+c{{execute interrupt}} and the program exit without printing any additional infomation.

Then we start math-game again：

java -jar math-game.jar{{execute T1}}
