## What is Math.random() Method in Java?

*The java.lang.Math.random() method returns a pseudorandom, “double” type number ranging from 0.0 to 1.0.*

```
0.0 ≤ random < 1.0
```

Kindly note, that the random number is greater than or equal to 0.0 and less than 1.0.
## How to Use Math.random() in Java?

Using the Math.random() method is pretty simple even for beginners.### Example 1

Let’s look at a basic example for a clear understanding.```
public class RandomTest {
public static void main(String[] args) {
double random1 = Math.random();
double random2 = Math.random();
System.out.println("First Random Number: " + random1);
System.out.println("Second Random Number: " + random2);
}
}
```

#### Output

First Random Number: 0.5486939400685561
Second Random Number: 0.23550115674999972

## Using random() Method within a Range

Calling Math.random() method looks pretty self-explanatory. However, our need for random numbers doesn’t always lie within the range of 0 and 1. For real-life problems, we can operate within other specified ranges as well. Let’s look at an example of using the Math.random() method for a given range, say 1 to 50.### Example 2

```
public class RandomNumberInRange {
public static int getRandom(int min, int max) {
int range = (max - min) + 1;
int random = (int) ((range * Math.random()) + min);
return random;
}
public static void main(String[] args) {
// Let's play Ludo with 4 Players
int dieRoll = getRandom(1, 6);
System.out.println("Red's Turn: " + dieRoll);
dieRoll = getRandom(1, 6);
System.out.println("Blue's Turn: " + dieRoll);
dieRoll = getRandom(1, 6);
System.out.println("Green's Turn: " + dieRoll);
dieRoll = getRandom(1, 6);
System.out.println("Yellow's Turn: " + dieRoll);
}
}
```

#### Output

Red's Turn: 3
Blue's Turn: 2
Green's Turn: 6
Yellow's Turn: 4
