Given:
public class ScopeTest {
int j, int k;
public static void main(String[] args) {
ew ScopeTest().doStuff(); }
void doStuff() {
nt x = 5;
oStuff2();
System.out.println("x");
}
void doStuff2() {
nt y = 7;
ystem.out.println("y");
or (int z = 0; z < 5; z++) {
ystem.out.println("z");
ystem.out.println("y");
}
Which two items are fields?

Given:
package p1;
public interface DoInterface {
void method1(int n1); // line n1
}
package p3;
import p1.DoInterface;
public class DoClass implements DoInterface {
public DoClass(int p1) { }
public void method1(int p1) { } // line n2
private void method2(int p1) { } // line n3
}
public class Test {
public static void main(String[] args) {
DoInterface doi= new DoClass(100); // line n4
doi.method1(100);
doi.method2(100);
}
}
Which change will enable the code to compile?
