How to Create a Random Long Value in Java?

Java – Create Random Long Value

To create a random long value in Java, use Random.nextLong() method. Create java.util.Random class object and call nextLong() method on this object. nextLong() returns a randomly generated long value.

In the following example, we will create a random long value using nextLong() method.

Java Program

import java.util.Random;

public class Example{ 
    public static void main(String[] args) {
    	Random random = new Random();
    	long l = random.nextLong();
    	System.out.println("Next random long value is : " + l);
    }
}

Output

Next random long value is : 5015315584966125576

Reference to Random.nextLong() method for syntax and more example programs.

Conclusion

In this Java Tutorial, we learned how to create a random long value using java.util.Random.nextLong() method.
