    Multiple Inheritance is not a concept in Java programming. Java only supports single inheritance, which means a class can only inherit from one superclass. Multiple Inheritance refers to a feature in some programming languages where a class can inherit from multiple superclasses. Java does not support this feature to avoid the diamond problem and maintain code simplicity and clarity.

    • Lokal

    • Instance

    • Class

    • Konstruktor

    • Kunci

    Correct Answer
    A. Instance
    Explanation
    The explanation for the correct answer, which is "Instance," is that an instance variable is a variable that is declared within a class but outside of any method. It is used when the class is loaded and each instance of the class has its own copy of the instance variables. These variables hold the state or data associated with each individual object of the class.

    Teknik yang digunakan untuk penggunaan objek yang tidak diperlukan untuk dimusnahkan (dikembalikan ke pool memori) disebut :

    • Finalysasi Objek

    • Penghancuran Objek

    • Pemusnahan Objek

    • Garbage Collection

    • Kelas Objek

    Correct Answer
    A. Garbage Collection
    Explanation
    Garbage Collection is the technique used for reclaiming memory by automatically identifying and freeing up objects that are no longer needed in a program. It involves the process of identifying and deleting unused objects, freeing up memory space, and making it available for future use. This helps in optimizing memory usage and improving the performance of the program by preventing memory leaks and reducing the burden of manual memory management.

  • 12. 

    Dengan menciptakan instan/objek dengan tipe / kelas dan memberikan variabel. mengacu atau bertindak sebagai reference ke objek tersebut membuat program menjadi 

    • Lebih mudah dibaca

    • Singkat dan jelas

    • Lebih efisien karena objek telah diinisiasi dengan nilai

    • Lebih berfungsi ganda

    • Dapat didefinisikan

    Correct Answer
    A. Lebih efisien karena objek telah diinisiasi dengan nilai
    Explanation
    By creating an instance/object with a type/class and assigning variables to refer to or act as a reference to that object, the program becomes more efficient because the object has already been initialized with a value. This means that the program does not need to allocate additional memory or perform extra operations to initialize the object when it is needed. This can improve the overall performance and efficiency of the program.

    Garbage Collection secara otomatis membebaskan sumber daya memory yang digunakan objek. Tapi objek dapat juga memegang sumber daya jenis lain seperti  

    • Instance Method

    • Network Connection

    • File Finalizer

    • File, Descriptor atau Socket

    • Thread di Background

    Correct Answer
    A. File, Descriptor atau Socket
    Explanation
    Garbage collection automatically frees up memory resources used by objects. However, objects can also hold other types of resources such as file descriptors or sockets. These resources need to be explicitly released by the programmer to avoid resource leaks. Therefore, file, descriptor, or socket resources are not automatically freed by garbage collection.

    Ada beberapa kelas dan interface pada program multithreaded yaitu thread, threadbeath, threadgroup, runnable. Pengertian dari threadgroup adalah 

    • Untuk menciptakan thread eksekusi diprogram

    • Untuk membersihkan yang telag berakhir eksekusinya

    • Untuk mengelompokkan sekelompok threads

    • Alternatif penciptaan thread menjadi sub kelas thread

    • Untuk menghapus thread eksekusi program

    Correct Answer
    A. Untuk mengelompokkan sekelompok threads
    Explanation
    ThreadGroup digunakan untuk mengelompokkan sekelompok thread. Dengan menggunakan ThreadGroup, kita dapat mengatur dan mengendalikan sekelompok thread secara bersamaan. ThreadGroup juga memungkinkan kita untuk melakukan operasi seperti menonaktifkan, menghentikan, atau menghentikan semua thread dalam grup dengan mudah. Dengan cara ini, kita dapat mengorganisir dan mengelola thread secara efisien dalam program multithreaded.

    Salah satu konsep penting orientasi dan mempunyai dampak langsung pada cara merancang dan menulis kelas merupakan 

    • Abstraksi

    • Modularasi

    • Pewarisan

    • Hirarki

    • Konkurensi

    Correct Answer
    A. Pewarisan
    Explanation
    Pewarisan adalah konsep penting dalam orientasi dan memiliki dampak langsung pada cara merancang dan menulis kelas. Dalam pewarisan, sebuah kelas dapat mewarisi properti dan metode dari kelas lain yang disebut kelas induk atau superclass. Hal ini memungkinkan untuk mengatur hubungan hierarki antara kelas-kelas dan memungkinkan untuk menghindari duplikasi kode. Dengan menggunakan pewarisan, kita dapat memperluas atau mengubah fungsionalitas kelas induk tanpa harus mengubah kode di kelas anak.

    Berikut yang bukan merupakan karakteristik unik yang membantu mengabstraksikan kelas adalah 

    • Responsibilities

    • Sequentially

    • Persistence

    • Tangibility

    • Integrity

    Correct Answer
    A. Responsibilities
    Explanation
    The given options are characteristics that help in abstracting a class. Responsibilities, Sequentially, Persistence, and Integrity are all characteristics that contribute to the abstraction of a class by defining its behavior, order of execution, data storage, and consistency. Tangibility, on the other hand, is not a characteristic that directly contributes to the abstraction of a class. It refers to the physical nature or touchability of an object, which is not relevant in the context of abstracting a class.

    • Abstraksi

    • Pesan

    • Pengapsulan

    • Hirarki

    • Typing

    Correct Answer
    A. Pesan
    Explanation
    The correct answer is "Pesan". In object orientation according to Booch, principles such as abstraction, encapsulation, hierarchy, and typing are fundamental. However, "Pesan" (which means "message" in English) is not considered a fundamental principle of object orientation.
