Thread: What does this line in the code mean?

What does this mean?

static {
		cache = new Cache(); 
	}

The whole class is as:

public class ServiceLocator {
   private static Cache cache;
 
   static {
      cache = new Cache();		
   }
 
   public static Service getService(String jndiName){
 
      Service service = cache.getService(jndiName);
 
      if(service != null){
         return service;
      }
 
      InitialContext context = new InitialContext();
      Service service1 = (Service)context.lookup(jndiName);
      cache.addService(service1);
      return service1;
   }
}

So what is the role of this code in the application? (Is it a nameless static method? What is it called?)

This code creates an instance of Cache and assigns the reference of Cache to that instance to a variable.
This is in a static block.
The specialty of the static block is:
1. When objects created separately there is no need to call static block because it is associated with the class level.
2. Static blocks are executed before the constructor and main function. Automatically managed by JVM that's why this block is nameless.
3. It is used to initialize static data members. The static block gets executed when the class is loaded in the memory before the main().

Thanks for explaining!
