First of all, I was unsure what the title of this question should be so I just gave it my best shot. I just started using Eclipse as my IDE, it's a great IDE and all but I get annoyed when I highlight a portion of code to be edited or replaced, any code after it gets deleted. So for example:

System.out.println(theScanner.nextLine());

I want to replace nextLine with nextDouble. I would highlight nextLine and type in nextDouble but then the ()()(); would be erased and I would have to type them in again. Is there a way to fix this?
