A: JOptionPane doesn't show; application combines Swing and console. Apparently the JOptionPane is behind eclipse as it not not the top windows. It does "show" but only behind eclipse. Thanks FractionalRadix (more) |

no, I don't see any error.
But FractionalRadix is right. The problem is that the JOptionPane is created behind eclipse and is hidden. (more) |

you are right.
Thank you.
That was the problem. it was hidden behind eclipse so it looked to me as if the program stack. (more) |

in other word, interpreter always compile the code (including all step of compilation like parsing) and then run it. because the cpu run in any case can run only the machine code.
So to say that the difference is whether the code is compiled once and kept as compiled binary or the source cod... (more) |

By "compile," I guess you mean translating to machine code and executing it. But that is what happens every time an interpreter runs. It translates the script into machine code and then runs it. But in the case of compilation, like in C, it creates a binary shared library or a file once, and then... (more) |

A: What are the criteria to define if a programming language is compiled or interpreted? if the code is compiled everytime before running, then it is interpreted.
