Given the following code for a Planet object:

What is the output?

Given the code fragments:

Which code fragment, when inserted at line ni, enables the code to print Hank?

Given:
public class ComputeSum {
public int x;
public int y;
public int sum;
public ComputeSum (int nx, int ny) {
x = nx; y =ny;
updateSum();
}
public void setX(int nx) { x = nx; updateSum();}
public void setY(int ny) { x = ny; updateSum();}
void updateSum() { sum = x + y;}
}
This class needs to protect an invariant on the sum field.
Which three members must have the private access modifier to ensure that this invariant is maintained?

Given:
public class Natural {
private int i;
void disp() {
while (i <= 5) {
for (int i=1; i <=5;) {
System.out.print(i + " ");
i++;
}
i++;
}
}
public static void main(String[] args) {
new Natural().disp();
}
}
What is the result?

Given the code fragment:

Assume that the system date is June 20, 2014.
What is the result?
