If a class is declared final, you cannot inherit it. If you try it gives you a compile-time error as − Example final class Super { private int data = 30; } public class Sub extends Sub { public static void main(String args[]){ } } Output Exception in thread "main" java.lang.Error: Unresolved compilation problem: at Sub.main(Sub.java:7)
Boolean literals represent only two values true or false. And in Java the value of 1 is assumed as true and the value of 0 is assumed as false. Example Live Demo public class Test{ public static void main(String args[]) throws Exception{ boolean bool1 = true; boolean bool2 = false; boolean bool = (25==(100/4)); System.out.println(bool1); System.out.println(bool2); System.out.println(bool); } } Output true false true
There is a table TFDIR which contains all the information. You can use this table with FMODE=’R’ by transaction SE16. R denotes remote functions. If you want to check the return values of the function, you can use transaction SE37 by inputting the function in the search field.
Java tokens are smallest elements of a program which are identified by the compiler. Tokens in java include identifiers, keywords, literals, operators and, separators.

NUMC is numeric text. As this is text, SUM function cannot be implemented as it is of type varchar in the database.There is no simple solution to do it. The one method is to copy the data to internal tables, convert the NUMC data into DEC by looping through all the rows, SUM and GROUP them and then convert back the DEC values back to NUMC values.
