Overloading is the mechanism of binding the method call with the method body dynamically based on the parameters passed to the method call. If you observe the following example, it contains two methods with same name, different parameters and if you call the method by passing two integer values the first method will be executed and, if you call by passing 3 integer values then the second method will be executed.It is not possible to decide to execute which method based on the return type, therefore, overloading is not possible just by changing the return type of the method.

There would not be much of difference in both ways. The only thing is without AT_FIRST, the counter variables will be cleared in all cases while using AT_FIRST, the counter variables will be cleared only if there is at least one execution of the loop. So, the only difference would come into the picture if ls_itab is empty.

If a function is inline, the compiler places a copy of the code of that function at each point where the function is called at compile time. Any change to an inline function could require all clients of the function to be recompiled because compiler would need to replace all the code once again otherwise it will continue with old functionality. No, Java does not provide inline functions it is typically done by the JVM at execution time.
