Answer 1

The debugger in Eclipse will automatically suspend execution (and let you inspect variables/step/resume etc) if an uncaught exception is thrown.

Enter for instance the following program...

public class Test {

    public void methodA() {
        methodB("hello");
        methodB(null);
    }

    public void methodB(String s) {
        System.out.println(s.substring(2));
    }

    public static void main(String[] args) {
        new Test().methodA();
    }
}

... and click the little "bug"-icon or choose Run -> Debug As -> Java Application
