Where did you declare number? You need to create a variable called number and assign the integer value of name to it.

Also "throws java.io.IOException" will still cause it to crash if there is an exception.

Hope that helps.

You are trying to multiply a string by a number. Imagine, what is "hello"*3? It doesn't make sense[1].

To do this, you'll have to either read as an integer (instead of a string), or convert the string to an integer after reading.

[1] Some languages will actually give you "hellohellohello" for this
