only one instance of a class is created, create a private default constructor to avoid outside modification. only one instance of a class is created we make SingletonPattern as static. public Class A { private static A a ; private A() { } ; public static synchronized A getA() { if (a == null ) { a = new A() ; } return a ; } }
