When you use an %IF-%THEN statement in your macro program

data test; a='A dataset'; run; %macro opends(name); %if %sysfunc(exist(&name)) %then %do; %let dsid=%sysfunc(open(&name,i)); %put data set &name; %end; %else %put Data set &name does not exist.; %mend opends; %opends(null); %opends(test); What will be written in the Log?

You can avoid re-typing doc comments by being aware of how the Javadoc tool duplicates (inherits) comments for methods that override or implement other methods. This occurs in three cases:

What should be the order of the @param tag when there are multiple parameters in the declaration ?

Which of the following tag is mandatory while using the Javadoc tool ?

Which tag is synonymous to the @throws tag ?

Which tag adds a comment indicating that the API should no longer be used ?

Identify whether the following statement is true or false.
The finally block is executed when an exception is thrown, even if no catch matches it.

What is the output of the following,
...
StringBuffer sb1 = new StringBuffer("Debopam");
StringBuffer sb2= new StringBuffer("Debopam ");
String ss1 = " Debopam ";
System.out.println(sb1==sb2);
System.out.println(sb1.equals(sb2));
System.out.println(sb1.equals(ss1));
System.out.println("Poddar".substring(3));
...

What is main objective of Component Based Development (CBD) approach?
