Singletonclass is a class which can be instantiated only once.
public class Singleton
{
private static single = new Singleton();

Private Singleton();
{}
}

For a singleton class, the constructor is made private and
a static variable is used for instatiating the class.

take an array with -ve and +ve value both.find out the nearest value of 0(zero).if two values are same like(-2 and +2)then extract +2 is nearest of 0(zero).
