# Generate random Integer within given range

In this example we shall show you how to generate a random Integer within a given range, using `random()` method of Math. The class Math contains methods for performing basic numeric operations such as the elementary exponential, logarithm, square root, and trigonometric functions. To generate a random Integer within a given range one should perform the following steps:

• Use `random()` method of Math to get a double value with a positive sign, greater than or equal to 0.0 and less than 1.0.
• Multiply the result to a number. For example, multiply the result to 100. The maximum of this is 100 and the minimum 0.
• You can also add a number to the result. For example add 50 to the result. Now the range is between 50 and 150,

as described in the code snippet below.

```package com.javacodegeeks.snippets.core;

public class RandomIntWithinGivenRange {

public static void main(String args[]) {

// This example will return a random integer
// in the range [-50,50]
int random1 = (int)(Math.random()*100)-50;
System.out.println("Value 1 = " + random1);

// This example will return a random integer
// in the range [50,150]
int random2 = (int)(Math.random()*100)+50;
System.out.println("Value 2 = " + random2);
}
}
```

Output:

``````Value 1 = -43
Value 2 = 111```
```

This was an example of how to generate a random Integer within a given range in Java.
