For Integer.parseInt you can use std::stoi, std::istringstream, sscanf, atoi etc.

For String.valueOf() alternatives, you can std::ostringstream, sprintf, std::tostring etc.

Recommendations:
c++11 stoi and tostring
c++ istringstream and ostringstream
c atoi and sprintf

You may use atoi c++ function.

int atoi (const char * str);

Convert string to integer Parses the C-string str interpreting its content as an integral number, which is returned as a value of type int.
