What is vector in java?
victor is growvable object.. victor is legacy class it will support the iterator and enumarotor interfaces it is synchonyzied it will support like hasMoreElemetns and hasNext element
What are math functions in java?
Math is a pre-defined class in the package java.lang. It contain various predefined functions in it that help the users to carry out various mathematical operations in their programs. Various Math Functions are:: Math.pow(x,y) => x^y Math.sqrt(x) => Square root of 'x' Math.tan(x),sin(x),cos(x) => tan, sin, cos of 'x' respectively there are also other functions like Math.ceil,Math.floor,Math.mod,etc.
What makes up a Java class?
Fields and methods. Fields are variables defined at the class level, i.e., they are available for all methods. Methods are the equivalent of functions / procedures, but they are defined for a specific class.
Do you use virtual functions in Java?
Every method in java that isn't a class (static) method is automatically "virtual." If you want to disable virtual overrides, make the method "final" in the base class.
Define iterator in java?
An Iterator is a java feature using which we can loop through every single element of a collection and perform operations on them. It is extremely useful because we don't have to worry about the collection size or whether we will get index out of bounds exceptions while looping through a collection Ex: ArrayList lst = new ArrayList(); //code that populates the list Iterator ir = lst.iterator(); Here itr is the iterator that will help the code loop through each element of the collection.
Where is it possible to get a Java iterator?
The Oracle website has a step by step pattern that shows how to obtain an iterator for use with Java programming. HashMap can also be helpful with explaining the looping sequence.
What is function in java terminology?
In Java, a function is called a "method". In Java as well as other languages, a method is a function defined specifically for one class. In Java, this is the only way to define functions, therefore, all functions are methods.In Java, a function is called a "method".

What is the use of functions in java?
Same as in other languages. To organize commands into logical pieces. However, in Java the functions are called "methods". This is related to the fact that in Java, methods or functions are defined as part of a class.

What is difference Iterator and Enumeration?
1.Iterator has remove method while enumeration doesn't have it. 2.Iterator is new in Java API but Enumeration is older one. 3. Iterator extends functionality of Enumeration. 4. Iterator is more secure and safe as compared to Enumeration because it does not allow other thread to modify the collection object while some thread is iterating over it and throws ConcurrentModificationException.
What is Re usability in java?
Reusability in Java means that once you write some code, you can use it over and over again - if you write it so that it can be reused. For example, if you write a Enumeration-Iterator adapter, or some code that lets you treat an Enumeration - Java legacy code - as an Iterator - shiny NEW Java code - then you can use it not only in your animal simulation program, but also in your Jacuzzi interface program.
What is math in java programming?
The java. lang. math class allows for the use of many common mathematical functions that can be used while creating programs
Extension file for Java?
Java source files have the .java extension, compiled Java class files have the .class extension.
How do I create an iterator class for iterating over a Pair(EInteger) object that returns E however many times Integer object is set to before moving to the next Pair object in Java?
The website wont let me words this in a reasonable manor in the question so, How do I create an iterator class for iterating over an ArrayList of Pair<E,Integer> objects that returns E however many times the Integer object is set to before moving to the next Pair object in java. For example if I have two Pair objects in the ArrayList, one containing < "A" , 4 > and one < "B" , 2 > then calling next in my iterator should return one A the first call, another A the second call, etc. before moving onto B when all 4 have been returned. I understand how to write the iterator class itself ( contstructor, hasNext, next, and remove) but what should the logic be in the next() method?
Prog to display array element?

What are methods and how are these related to an object?
Methods are functions defined for a class. Therefore they are accessible for all objects based on the class (depending on visibility; for example in Java: if they are public).
