Komentar ini penting untuk diketahui karena dapat berfungsi sebagai penjelas kode yang kita buat.\n\nJava memiliki beberapa jenis komentar, yaitu:\n\n* Komentar satu baris (single line comment)\n* Komentar banyak baris (multiline comment)\n* Komentar dokumentasi (doc comment)\n\nMari kita bahas lebih lanjut.\n\n## Tentang Komentar pada Bahasa Java\n\nKomentar atau ***comments*** merupakan blok kode yang tidak akan dibaca dan tidak akan dieksekusi oleh komputer. Walau begitu, komentar ini memiliki fungsi yang penting.\n\nKomentar berfungsi untuk membantu programmer mengerti maksud dari kode yang telah ditulis.\n\nKetika menulis program, pasti kita tahu betul apa maksud kode yang kita ketikkan. Tapi apa yang terjadi jika kode itu ditinggal selama sekian hari atau bahkan sekian tahun?\n\nKarena programmer juga manusia, dan manusia tidak luput dari lupa, besar kemungkinan kita akan lupa maksud dari kode yang kita tulis. Apalagi jika kode yang ditulis semrawut dengan penamaan yang tidak jelas. Wahh... susah 😞.\n\nDi sinilah pentingnya menulis komentar. Dengan komentar, kita bisa mendeskripsikan kode yang kita tulis dalam bahasa manusia yang tentu lebih manusiawi dari bahasa komputer.\n\nSelain untuk itu, komentar juga dapat berfungsi sebagai sarana debugging kode. Kita dapat memerintahkan komputer untuk mengabaikan baris kode tanpa perlu menghapusnya.\n\n## Penulisan Komentar pada Bahasa Java\n\nKita bisa menempatkan komentar di mana saja sesuka kita. Dalam komentar juga dapat ditulis apa saja yang kita inginkan. Tidak harus kode program. Menulis puisi dalam comment juga tidak masalah.\n\nUntuk menulis komentar, Java memiliki 3 sintaks yang berbeda, yaitu:\n\n### Komentar Satu Baris (*Single Line Comments*)\n\nSeperti namanya, komentar ini hanya bisa ditulis dalam satu baris saja.\n\nPenulisan komentar satu baris diawali dengan tanda `\u002F\u002F`. Contoh:\n\n```java\n\u002F\u002F Ini adalah komentar satu baris\n\u002F\u002F Kode ini di luar blok kelas\n\npublic class HelloWorld {\n  \u002F\u002F Kode ini di dalam blok kelas HelloWorld\n  public static void main(String args[]) {\n    \u002F\u002F Kode ini di dalam blok fungsi main\n    System.out.println(\"Hello World!\"); \u002F\u002F Baris ini mencetak \"Hello World\"\n  }\n}\n```\n\nJika kode tersebut dijalankan, pasti tidak akan ada perubahan dari sebelumnya. Ini karena komentar tidak dieksekusi oleh komputer.\n\n### Komentar Banyak Baris (*Multi Line Comments*)\n\nDengan *multi line comments* kita bisa menuliskan satu atau beberapa baris komentar dalam satu blok comment.\n\nAturan penulisannya adalah dibuka dengan `\u002F*` dan ditutup dengan `*\u002F`. Contoh:\n\n```java\n\u002F* Ini adalah komentar banyak baris\nKode ini di luar blok kelas *\u002F\n\npublic class HelloWorld {\n  \u002F*\n    Kode ini di dalam blok kelas HelloWorld\n    ini baris komentar baru\n    tetap dalam blok komentar yang sama\n  *\u002F\n  public static void main(String args[]) {\n    \u002F*\n      Fungsi utama ini akan dipanggil pertama kali\n      oleh komputer. Kode di bawah bertujuan untuk\n      mencetak \"Hello World\" di layar konsol\n    *\u002F\n    System.out.println(\"Hello World!\");\n    \u002F* multi line comment juga bisa digunakan untuk komentar satu baris *\u002F\n  }\n}\n```\n\n### Komentar Dokumentasi (*Doc Comments*)\n\nYang terakhir ada komentar dokumentasi.\n\nKomentar ini memiliki fungsi khusus untuk membuat dokumentasi kode yang kita buat. Java memiliki alat yang bernama **JavaDoc** untuk membuat dokumentasi dari komentar.\n\n*Doc comments* memiliki sintaks seperti *multi line comments*, hanya yang membedakan adalah pembukanya yaitu `\u002F**` dan setiap baris komentar harus diawali tanda `*`. Contohnya:\n\n```java\n\u002F**\n* Kelas utama program \"Hello World\"\n* @author Inva\n*\u002F\npublic class HelloWorld {\n  \u002F**\n  * Fungsi utama yang akan dipanggil oleh komputer\n  * Berfungsi untuk mencetak \u003Ccode>Hello World\u003Ccode> di layar konsol\n  * @params tidak ada parameter yang idpakai\n  * @return tidak mengembalikan apa-apa\n  *\u002F\n  public static void main(String args[]) {\n    System.out.println(\"Hello World!\");\n  }\n}\n```\n\nPenulisan komentar jenis ini tidak boleh sembarangan, ada spesifikasi tersendiri dari JavaDoc. Untuk lebih lanjut bisa di lihat di laman [panduan JavaDoc](https:\u002F\u002Fwww.oracle.com\u002Ftechnical-resources\u002Farticles\u002Fjava\u002Fjavadoc-tool.html).\n\nKarena fungsinya yang spesifik, kita tidak akan menggunakan komentar dokumentasi dalam Seri Belajar Java ini.\n\n## Selanjutnya\n\nKomentar memang tidak berguna di mata komputer, tetapi sangat membantu programmer membaca programnya. Jadi jangan sungkan untuk menulis komentar.\n\nPada kesempatan-kesempatan selanjutnya kita akan sering melihat komentar menyelingi kode yang kita buat, jadi jangan sampai bingung ya. Itu hanya penjelas, tidak ditulis pun tidak apa-apa.\n\nSelanjutnya kita akan membahas tentang sistem output pada bahasa Java.\n\nSelamat berkoding ria 👋\n","\u003Cp>Pada kesempatan kali ini kita akan membahas tentang komentar pada Java.
