Untuk menjalankan program ini harus mempunyai java yaitu j2sdk, atau jdk "untuk java", untuk menyimpan filenya ketik nama_file.java simpan di folder "bin" pada software javanya. Dan untuk menjalankan serta mengcompile buka "CommandPrompt", buka folder bin di software javanya, Cara Compile ketik "javac nama_file.java" tdk memakai tanda kutip dan cara run atau menjalankan ketik "java nama_file".

Penjelasan singkat pada kode tersebut :

Program ini menggunakan package awt, swing, util. Program ini akan mengeluarkan seperti dibawah ini ..
