Answer:
Hi there Rumanruxi! The error is in the if statement "if(userNum = 2)". 
Explanation:
The if statement in this Java code is assigning userNum the value of 2 instead of comparing it with the value of 2. For equals comparison we need to write two equals "==" in the statement as: "if (userNum == 2)". This will return true if userNum is 2 otherwise it will return false.
