In this example, we will see how the main method is defined. Code: packagecom.edubca.javademo;publicclassJavaDemo{publicstaticvoidmain(String args[]){String str="This is Edubca Java Training";System.out.println(str);//printing on console}} ...
The syntax for nesting an interface within a class is reasonably obvious, and just like non-nested interfaces, these can havepublicor package-access visibility. You can also see that bothpublicand package-access nested interfaces can be implemented aspublic, package-access, andprivatenested classes...
