question 41)

given the following code what will be output?

public class pass{
    static int j=20;
    public static void main(string argv[]){
 int i=10;
 pass p = new pass();
 p.amethod(i);
 system.out.println(i);
 system.out.println(j);
    }

    public void amethod(int x){
 x=x*2;
 j=j*2;
    }
}

1) error: amethod parameter does not match variable
2) 20 and 40
3) 10 and 40
4) 10, and 20

question 42)
what code placed after the comment //for loop would result in the population of every element of the array ia[] with a value from variable i.?

public class lin{
    public static void main(string argv[]){
 lin l = new lin();
 l.amethod();
    }
    public void amethod(){
 int ia[] = new int[4];
 //start for loop
 {
     ia[i]=i;
     system.out.println(ia[i]);
 }
    }
}

1) for(int i=0; i < ia.length() -1; i++)
2) for (int i=0; i< ia.length(); i++)
3) for(int i=1; i < 4; i++)
4) for(int i=0; i< ia.length;i++) 2]
