If you are reading this then, you should have knowledge about Design Patterns in programming languages. Because, Singleton Pattern is one of the types in design patterns.
Singleton Pattern in java means we have to make a class with which we can create only a single object, not more than one.
So, here i'm giving you the code of writing a java class
public class SingletonClass
{
private static SingletonClass obj = null;
private SingletonClass(){}
public static SingletonClass getInst()
{
if(obj==null) {
obj = new SingletonClass();
}
return obj;
}
protected static void show()
{
System.out.println(obj);
}
}
public class mainClass
{
public static void main(String[] args)
{
SingletonClass ref = SingletonClass.getInst();
ref.show();
}
}
