Java Math.random() Method Example 1


public class MyClass  
{  
    public static void main(String[] args)   
    {  
        double x = Math.random();  
        double y = Math.random();  
        System.out.println(x);  
        System.out.println(y);  
    }  
}  

Output:

Java Math.random() Method Example 2


public class MyClass 
{  
    public static void main(String[] args)   
    {  
        double x = Math.random() * 15;  
        double y = Math.random() * 15;  
        System.out.println(x);  
        System.out.println(y);  
    }  
}
