Answer 1

For the First error can you try something like this:

(this.height = this.height - 160);

The error indicates you are trying to make an assignment operation but you have not put a variable in the left hand side of the equation. there may also be a short hand way to do this such as:

(this.height =- 160);

for the second error is seems that you have declared "localObject" as an Object. can you just declare it as a String. seems that you are assigning a string to it and then wanting to return a string. See if that works.
