First, a singleton class has only one instance. That can be achieved by
providing only  a private constructor, and accessing the only class instance
using a static method which will return a static member initialized by the
private constructor. The static private variable will be initialized only
once. See example:

public class testSingleton  {

    /* this for test only */
    private int instances = 0;

    private static testSingleton instance  = new testSingleton();

    private testSingleton() {
        /* it will be incermented one time only */
        instances++;
        /* some initialization stuff  */
    }

    public static testSingleton getInstance () {
        System.out.println("Number of instances :" + instances);
        return instance;
    }

    /* other class stuff */
}
