question 51)

what will happen when you compile and run the following code?

public class scope{
    private int i;
    public static void main(string argv[]){
 scope s = new scope();
 s.amethod();
    }//end of main
    public static void amethod(){
 system.out.println(i);
    }//end of amethod
}//end of class

1) a value of 0 will be printed out
2) nothing will be printed out
3) a compile time error
4) a compile time error complaining of the scope of the variable i

question 52)
you want to lay out a set of buttons horizontally but with more space between the first button and the rest. you are going to use the gridbaglayout manager to control the way the buttons are set out. how will you modify the way the gridbaglayout acts in order to change the spacing around the first button?
 

1) create an instance of the gridbagconstraints class, call the weightx() method and then pass the gridbagconstraints instance with the component to the setconstraints method of the gridbaglayout class.
2) create an instance of the gridbagconstraints class, set the weightx field and then pass the gridbagconstraints instance with the component to the setconstraints method of the gridbaglayout class.
3) create an instance of the gridbaglayout class, set the weightx field and then call the setconstraints method of the gridbaglayoutclass with the component as a parameter.
4) create an instance of the gridbaglayout class, call the setweightx() method and then pass the gridbagconstraints instance with the component to the setconstraints method of the gridbaglayout class.
