Note that all expressions in thefor-loopare optional. In case, we do not provide theterminationexpression, we must terminate the loop inside the statements else it can result in aninfinite loop. 2. Java For-loop Example In the following program, we are iterating over an array ofintvalues....
3. Our tool suggests candidates of program fragments to be changed for the scalability-improving modifications by using a global analysis and the consistency tests. This addresses Prob- lems a) and b). 4. If the programmer accepts the candidates, the appropriate changes are made to all of ...
