回答1:
For this you need to configure the build path of your project. You probably achieve this if you move your project files into your eclipse work space. Click on the project in eclipse -> "Build Path >> Configure Build Path >>" now set up jre system library, if its already present then delete that and add a new jre library (from directory of program files). happy coding!!!!!
