In addition, Java is a dynamic language where you can safely modify a program while it is running, whereas C++ does not allow it. This is especially important for network applications that cannot afford any downtime. Also, all basic Java data types are predefined and not platform-dependent, ...
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 ...

programs use the most efficient integer type for each processor. As a result, a C program that runs well on a 32-bit processor may exhibit integer overflow on a 16-bit system. Since Java programs must run with the same results on allmachines, the ranges for the various types are fixed....
