Constructor overloading is not possible in java.True or False.

What is the difference between constructor injection and setter injection?

JAVA CODE Write a java set of classes that could be used to do simple calculations on geometricobjects. The set should include the following classes: a) Shapes ,containing abstract methods( a methods that is declared without animplementation) area and perimeter b) Rectangle, a subclass of Shape, containing a constructor (with parameters forlength and width) along with methods area and perimeter. c) Triangle, a subclass of Shape, containing a constructor (with parameters for the three sides of a triangle) along with methods area ( s = (a+b+c)/2, A = sqrt( s(s-a)(s-b)(s-c) ) ) and perimeter d) Square, a subclass of Rectangle, containing a constructor (with a parameter for thelength of a side) and methods that invoke the methods of the Rectangle class todetermine the perimeter and area of a square.

Given: interface B void methodA(); class C implements B { void methodB(){ } } everything is fine methodA should be overriden in class C O class C should be abstract O either b or c

What is a parameterized constructor?

//Language: Kotlin class Person(name:String, age:Int)class Student(name:String,major:String, age:Int) : Person(name,age) Why won't the code compile correctly? The constructor for the superclass is not called correctly. The arguments for a Student do not match those of a Person Person is not open Missing semicolons

Suppose a byte-addressable computer using set associative cache has 8M byes of main memory and a cache of 128 blocks, where each cache block contains 64 bytes. a) If this cache is 4-way set associative, what is the format of a memory address as seen by the cache, that is, what are the sizes of the tag, set, and offset fields? b) If this cache is 16-way set associative, what is the format of a memory address as seen by the cache

Please answer question. This is pertaining to Java programming language 3-20

Question: Mr. Hamza is working as an accountant in the Octal Company. He wants to calculate salary of his company employees. Develop a java program to calculate salary using the concept of abstract based on the following instructions. Save the project/file as AccountantYourID. A) Abstract Class name: YourFirstName_Octal Abstract Member Method: – to calculate and return salary salary() B) Class name: Employee extends YourFirstName_Octal Member variables: wage, noOfDays, bonus Member Method : – parameterized constructor to initialize member variables – to calculate and return salary salary = (wage3 * noOfDays) / 4 + bonus C) Controlling class : – To create an object of Employee – To print salary of the Employee – To print bonus of Employee

The solution is using the Java language

constructors and static method can be declared abstract? True or false

Create a Java program that has the following: Inheritance - Create a superclass and one or more subclasses that inherit properties and methods from the superclass. Polymorphism - Show polymorphism by using method overriding and method overloading. Provide an example of runtime polymorphism by creating objects of the subclasses and calling overridden methods. Encapsulation - Demonstrate the concept of encapsulation by applying access modifiers (private, protected, public) appropriately in your program. Abstraction - Utilize abstract classes and methods in your program to illustrate abstraction. Show examples of the following words: super, this, static, final
