Java Math

The Java Math section has many options that allow you to do math tasks on numbers.

Math.max(x,y)

The Math.max(x, y) method can be used to find the highest values of x and y:

Example

Math.max(5, 10);

Math.min(x,y)

The Math.min(x, y) method can be used to find the low value of x and y:

Example

Math.min(5, 10);

Math.sqrt(x)

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

Example

Math.sqrt(64);

Math.abs(x)

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

Example

Math.abs(-4.7);

Random Numbers

Math.random() returns a random number between 0.0 (combined), and 1.0 (special):

Example

Math.random();

For more control over a random number, e.g. you only want a random number between 0 and 100, you can use the following formula:

Example

int randomNum = (int)(Math.random() * 101);  // 0 to 100
