FTP is a commonly used protocol used to transfer files. There are many ready-made solutions; it might not be necessary to program it. On the other hand, you may need to integrate FTP into some other application. In other words, if you already decided to program in Java, you may need to add FTP capabilities to it.
What else can I help you with?
What in java is not serializable?
Objects that do not implement Serializable.
Is it possible to run java program without JVM?
No. Java programs run in the Java Virtual Machine (JVM) - without it your computer won't know how to handle Java bytecode.
What the advantages of using the Java Collection Framework?
The main advantage is that you don't have to implement those collections yourself. Java provides very efficient implementations for dozens of collections.
What Java interface do you implement to provide methods that are called as an XML document is processed by a SAX parser?
ContentHandler
Can you provide a solution to the diamond-square algorithm using Java and recursion?
Yes. It is possible to provide a solution to the diamond-square algorithm using Java and recursion.
What in java is not serializable?
Objects that do not implement Serializable.
Where can one find out how to implement threads using Java?
You can find out how to implement threads using Java through Stacker Overflow, Java Script Source, Java Code Geeks, Free Programming Resources and other websites. There are also tutorials on college sites as well as Youtube.
What is problem in multiple inheritance?
Java does not support direct multiple Inheritance. Harder to implement, not every language support it: C++ does, Java does not.
Is it possible to run java program without JVM?
No. Java programs run in the Java Virtual Machine (JVM) - without it your computer won't know how to handle Java bytecode.
What are the functions of an interface in Java?
To create an abstraction or a blueprint for a class to implement later.
What is a URL in java?
URL is not a java-specific term. It means "uniform resource locator"; informally, it is the same as an "Internet address" - for example, the address to access a Web page, or an FTP server.
Need of interface in java?
Interfaces are used in Java to accomplish most of the goals of Multiple Inheritance. For several reasons, Java only supports Single Inheritance for classes - i.e. a class can have only a single parent. The use of Interfaces is how Java attempts to implement most of the positives of the concept of Multiple Inheritance while avoiding its pitfalls.
What is the minimum number of interfaces that a java class can have?
Zero. By default they do not implement any interfaces.
Write a java program to implement stack in java?
You would need an array to store the actual stack. Better use an ArrayList or some other structure that you can redimension. You'll also need a variable to point to the "top of stack" - the last element added, which is the first element to be taken away.
What are the alternatives to inheritence in java?
Java does not support multiple inheritance; a subclass cannot have more than one parent. Java compensates for this with interfaces. A class can implement multiple interfaces, but can only extend one class.
What the advantages of using the Java Collection Framework?
The main advantage is that you don't have to implement those collections yourself. Java provides very efficient implementations for dozens of collections.
What Java interface do you implement to provide methods that are called as an XML document is processed by a SAX parser?
