Casting
While Loop
Input
Some simple Maths and figures

int i = 10;
float f = 10.25;

i = (int)f;

while loop
while (condition(s)) {

}

sum to n (from 1)

int sum = 0;
int n = 10;
int i = 1;

while (i < n) {
    sum += I;
    i += 1;
}

It is important to know who to 'walk' through the code.

int sum = 0;
int n = 10;
int i = 1;

while (i < n) {
    sum += I;
    i += 1;
}
System.out.Println(sum);


int sum = 0;
int n = 10;
int i = 1;

while (i < n) {
    sum += I;
    i += 1;
}
System.out.Println((float)sum);
boolean exit;

int sum = 0;
int n = 10;
int i = 1;

while(!exit) {
    sum += I;
    i += 1;
    if (i < n)exit = true;
}
System.out.Println((float)sum);


BMI calculation
–    Formula

BMI = mass/weight

Think
–    Formula
–    variable types
–    test values


Factorial (maximum of 12)
–    Formula
–    Variables
–    how many times?
–    Hold result, counter, temp

Speed of the Plane
700 km/hr → m/s

700 * 1000m/60 min
700 * 1000 m/3600s

194.4m/s

1 ) (Speed x 1000)/(60 * 60)

Math function

2 Velocity * Math.cos(angle)

angle.degreeAngle * Math.PI/180

Distance = velocity x time

time = distance / velocity
= 10.29s

Initial velocity

yVelocity * Math.sin(angle);

y = vy + (1/2)g(t^2)


Quadratic formula

x = (b +/ (b^2 – 4ac)^0.5)/(2a)

t = (vy +/(vy^2 – 5 * 4.9 * 2000)^0.5)/(2 * 4.9)

Square root
Math.sqrt
Power
Math.pow(base, 2)
