In the following code DEFAULT_CACHE_SIZE is declared later, but it is used to assign a value to String variable before than that, so was curious how is it possible?

public class Test  { 

public String getName() { 
return this.name; 
} 

public int getCacheSize() { 
return this.cacheSize; 
} 

public synchronized void setCacheSize(int size) {
this.cacheSize = size; 

System.out.println("Cache size now " + this.cacheSize); 
} 

private final String name = "Reginald"; 
private int cacheSize = DEFAULT_CACHE_SIZE; 
private static final int DEFAULT_CACHE_SIZE = 200; 
}
