This is regarding a system which is developed using the Legacy software C++
and which now needs to be converted to Java ofcourse without any major trade-offs
in the Design and Architecture.

1.Is there a conversion tool which helps converting the C++ code to Java
without any design issues?
2.Is manual conversion of code the only answer for this conversion of legacy
code to Java?
3.How is it that we handle the features that C++ offers and Java does'nt
such as Multiple Inheritance,Overloaded operators,Pointers,etc?

It would be of great help even if very little information is available on
your side with respect to the above queries.

Thanks in advance,
