Java Math.random()

Syntax of Math.random()

The syntax of the random() method is:

Math.random()

Note: The random() method is a static method. Hence, we can call the method directly using the class name Math.

random() Parameters

The Math.random() method does not take any parameters.

random() Return Values

• returns a pseudorandom value between 0.0 and 1.0

Note: The values returned are not truly random. Instead values are generated by a definite computational process that satisfies some condition of randomness. Hence called pseudo random values.

Example 1: Java Math.random()

In the above example, we can see that the random() method returns three different values.

Example 2: Generate Random Number Between 10 and 20

Output

Random Numbers between 10 and 20:
15, 13, 11, 17, 20, 11, 17, 20, 14, 14,

Example 3: Access Random Array Elements

Output

Random Array Elements:
67, 34, 77, 34, 12, 77,
