i. Generating a random integer between 1 and n

Explanation / Answer

a. Computing the larger of two integers
public int larger(int num1, int num2)
{
if(num1 > num2)
return num1;
else return num2;
}

b. Computing the smallest of three floating-point numbers
public float smallest(float num1, float num2, float num3)
{
if(num1 < num2 && num1 < num3)
return num1;
else if(num2 < num1 && num2 < num3)
return num2;
else return num3;
}

c)
private static boolean prime(int x){…}

d)private static boolean contains(String x, String y){...}

e)private static double balance(double initial, double rate, double years){...}

f)private static void printBalance(double initial, double rate, double years){...}

g)private static void printCalendar(int x, int y){...}

h)private static String weekday(int x, int y, int z){...}

i)private static int random(1, int n){...}
