int [][] myarray;
Above statement declares an array, but does not create the array object. True False
You can adjust the number of elementi in an array after it has been created. True False
A class can have multiple constructors and each constructor must accept a unique set of parameters. True False
Homework Answers
True: The statement int [][] myarray declare an array, but note create array object.
statement myarray = new int[10][10] will create array object.
False: Once the array was created can't change the size of array.
True: Each constructor have different signatuer. So each constructor must accept a unique set of parameters.

A class can have multiple constructors and each constructor must accept a unique set of parameters. True False If the superclass has more than 2 constructors that requires parameters, then the subclasses can inherit these constructors automatically and we donot need to write any constructors in the subclasses. True False An inner class can reference the data and methods defined in the outer class in which it nests, so you do not need to pass the reference of the outer...

In Java, Implement a class MyArray as defined below, to store an array of integers (int). Many of its methods will be implemented using the principle of recursion. Users can create an object by default, in which case, the array should contain enough space to store 10 integer values. Obviously, the user can specify the size of the array s/he requires. Users may choose the third way of creating an object of type MyArray by making a copy of another...

1. Create a UML diagram to help design the class described in Q2 below. Do this exercise before you attempt to code the solution. Think about what instance variables will be required to describe a Person class object; should they be private or public? Determine what class methods are required; should they be private or public?2. Write Java code for a Person class. A Person has a name of type String and an age of type integer.Supply two constructors: one will be...

A method called linearSearch(), which takes as parameters an array of int followed by three values of type int, and returns a value of type int. The first int parameter represents a key, the second int parameter represents a starting position, and the third int parameter represents an end position. If the key occurs in the array between the start position (inclusive) and the end position (exclusive), the method returns the position of the first occurrence of the key in...

1. What will be the value of x after the following code is executed? int x = 10, y = 20; while (y < 100) { x += y; } A. 90 B. 110 C. 210 D. This is an infinite loop 2. If a superclass has constructor(s): A. then its subclass must initialize the superclass fields (attributes). B. then its subclass must call one of the constructors that the superclass does have. C. then its subclass does not inherit...

1. Assume you have a Car class that declares two private instance variables, make and model. Write Java code that implements a two-parameter constructor that instantiates a Car object and initializes both of its instance variables. 2. Logically, the make and model attributes of each Car object should not change in the life of that object. a. Write Java code that declares constant make and model attributes that cannot be changed after they are initialized by a constructor. Configure your...
