Java Math

The Java Math class provides a variety of methods that allow you to perform mathematical operations on numbers.

Math.max(x, y)

The Math.max(x, y) method is used to find the highest value between x and y:

// Example
int highestSpeed = Math.max(120, 150); // Maximum speed between two vehicles

// Example

int highestSpeed = Math.max(120, 150); // Maximum speed between two vehicles

Math.min(x, y)

The Math.min(x, y) method is used to find the lowest value between x and y:

// Example
int lowestSpeed = Math.min(60, 90); // Minimum speed between two vehicles

// Example

int lowestSpeed = Math.min(60, 90); // Minimum speed between two vehicles

Math.sqrt(x)

The Math.sqrt(x) method returns the square root of x:

// Example
double engineEfficiency = Math.sqrt(49); // Square root calculation for efficiency rating

// Example

double engineEfficiency = Math.sqrt(49); // Square root calculation for efficiency rating

Math.abs(x)

The Math.abs(x) method returns the absolute (positive) value of x:

// Example
double distanceDifference = Math.abs(-35.7); // Absolute value of distance difference

// Example

double distanceDifference = Math.abs(-35.7); // Absolute value of distance difference

Random Numbers

The Math.random() method returns a random number between 0.0 (inclusive) and 1.0 (exclusive):

// Example
double randomValue = Math.random(); // Generates a random number

// Example

double randomValue = Math.random(); // Generates a random number

To gain more control over the random number, such as generating a number between 0 and 100, you can use the following formula:

// Example
int randomMileage = (int)(Math.random() * 101); // Random mileage between 0 and 100

// Example

int randomMileage = (int)(Math.random() * 101); // Random mileage between 0 and 100
