I am trying to understand what I am doing wrong in this java program. I have a switch statement that reads from a file. For example, the first file works so that I can choose option 3 and only get information that involves bear. The second file (habitat), I set up like the first. I have a delimiter setup and its range is new lines {2,} however it's not reading from the habitat file right. It reads the whole file, if I select case 1, and errors if I select any other option.

 

My second issue is nesting a if statement inside the while loop. Both files have a statement, that should trigger a pop-up warning. For example, if the program reads "*****," it should trigger the pop-up warning and display the statement attached to the asterisk ie, "Health Concern." The error that I get is I am using .equals on an incompatible type. But if I am comparing strings, .equals is preferred over ==./*
