In the following block of code, I am trying to print the properties whose location, monthlyRent, numberOfBedrooms defined in the Property class being equal to this method’s parameters in LettingAgent class. When I compiled, the error is occured in the if line where it says non-static method like getlocation() can’t be referenced from static context.

In the last method you define (formatted below):
on the line:
you’re calling the
getmethod of thePropertyvariable. I think that should beProperty.getMonthlyRent().One other thing, in Java you should name your variables differently than their class names. I would use something like
I know it’s a small change, but it makes a big difference in the readability of your code. You can read about other Java code conventions in Code Conventions for the Java Programming Language.
