Systems using Classpath: gcj

• Java front-end to the GCC compiler

  • Java ≃ C++
    • GCC backend performs ± same optimizations as with other languages (C, C++, Fortran, Ada, Pascal, Cobol, ...) → fast execution
    • Static compilation produces stand-alone executables
      • But Java is a dynamic language!
      • → Run-time library contains a simple bytecode interpreter for dynamically loaded classes
