The document compares C++ and Java programming languages. It discusses their origins, first releases, stable releases, influences, platforms, compilation, memory management, inheritance, overloading, libraries, documentation, threading, input/output, and differences in supporting features like pointers, goto, structures/unions, and parameter passing. C++ was created as an extension of C while Java was created at Sun Microsystems. They have both influenced many other languages.
