question 58)

what will happen when you attempt to compile and run the following code.

public class pvf{



static boolean paddy.

public static void main(string argv[]){

        system.out.println(paddy).

        }



}

1) compile time error
2) compilation and output of false
3) compilation and output of true
4) compilation and output of null

question 59)

which of the following statements are true?

1) the x,y coordinates of an instance of mouseevent can be obtained using the getx() and gety() methods
2) the x,y coordinates of an instance of mouseevent can be obtained using the x and y integer fields
3) the time of a mouseevent can be extracted using the gettime() method
4) the time of a mouseevent can be extracted using the getwhen method

question 60)

given the following code 



import java.io.*.



public class ppvg{

public static void main(string argv[]){

        ppvg p = new ppvg().

        p.fliton().

        }

        public int fliton(){

        try{

                fileinputstream din = new fileinputstream("ppvg.java").

                din.read().

        }catch(ioexception ioe){

		system.out.println("flytwick").       

        	return 99.

        }finally{

        	system.out.println("fliton").

        	}

        return -1.

        }

        

}

assuming the file ppvg.java is available to be read which of the following statements are true if you try to compile and run the program?

1) the program will run and output only "flytwick"
2) the program will run and output only "fliton"
3) the program will run and output both "fliton" and "flytwick"
4) an error will occur at compile time because the method fliton attempts to return two values
