Chapter 6.8, Problem 6.8.3CP
Given two method definitions,
public static double m(double x, double y)
public static double m(int x, double y)
tell which of the two methods is invoked for:
- a. doub1e z = m (4, 5) ;
- b. double z = m(4, 5.4) ;
- c. double z = m(4.5, 5.4) ;

Analyze the following code.
public class Test {
public static void main(String[] args){
System.out.printlin( m(2) );
public static int m( int num ) {
return num;
}
public static void m( int num ) {
System.out.printin( num );
}
The program has a compile error because the second m method is def
method.
The program runs and prints 2 once.
21. Consider the following method:
public static void sketch(int x1, int y1, int x2, int y2, int n)
(
if (n <= 0)
O
else
(
}
drawLine(x1, y1, x2, y2);
Assume that the screen looks like a Cartesian coordinate
system with the origin at the center, and that drawLine
connects (x1,y1) to (x2,y2). Assume also that x1, y1, x2,
and y2 are never too large or too small to cause errors.
Which picture best represents the sketch drawn by the
method call
int xm
(x1 + x2 + y1 - y2) / 2;
int ym (y1 + y2 + x2-x1) / 2;
sketch(x1, y1, xm, ym, n - 1);
sketch (xm, ym, x2, y2, n - 1);

Write a java program method that accepts a year as a parameter, the method then returns true or false if the entered year is a leap year or not.
You may calculate the leap year as follows:
1. If the year is evenly divisible by 4, go to step 2. Otherwise go to step 5.
2. If the year is evenly divisible by 100, go to step 3. Otherwise go to step 4.
3. If the year is evenly divisible by 400, go to step 4. Otherwise go to step 5.
4. The year is a leap year (it has 366 days).
5. The year is not a leap year (it has 366 days).
