1.We can create static class object like the below example.
class OuterClass
{
void outerMethod()
{
System.out.println("Inside in outerclass");
}

static class InnerClass
{
void innerMethod()
{
System.out.println("Inside in innerclass");
}

}
public static void main(String args[])
{
InnerClass iclass=new InnerClass();
InnerClass iclass1=new InnerClass();
iclass.innerMethod();
}
}

public class MySingleTon {

private static MySingleTon myObj;
/**

*/
public static MySingleTon getInstance(){
if(myObj == null){
myObj = new MySingleTon();
}
return myObj;
}

public void getSomeThing(){
// do something here
System.out.println("I am here....");
}

public static void main(String a[]){
MySingleTon st = MySingleTon.getInstance();
