Check if a variable is between two numbers with Java

Question

I have a problem with this code:

if (90 >>= angle =<< 180)

The error explanation is:

The left-hand side

Answer 1

<<= is like +=, but for a left shift. x <<= 1 means x = x << 1. That's why 90 >>= angle doesn't parse. And, like others have said, Java doesn't have an elegant syntax for checking if a number is an an interval, so you have to do it the long way. It also can't do if (x == 0 || 1), and you're stuck writing it out the long way.
