Answer #1

What are the legal array index values?
Legal index values are 0 to size-1. if size is 5 than legal indexes are 0,1,2,3,4

What is a bounds error?
If we try to access any illegal index in the array than we will get bound error

What is an instance method, and how does it differ from a static method?
instance methods are object methods which requires object to invoke at.. they are availale for each object as differetncopy
static methods are class level methods these are common to all objects and these methods can be called using class name

How many constructors can a class have?
class can have any number of constructors
Can you have a class with no constructors?
yes we can write but compiler will add the default constructor to it
If a class has more than one constructor, which of them gets called?
It depends on the arguments your passing while creating the object

This laboratory assignment involves implementing a data structure called a map. A map associates objects called keys with other objects called values. It is implemented as a Java class that uses arrays internally. 1. Theory. A map is a set of key-value pairs. Each key is said to be associated with its corresponding value, so there is at most one pair in the set with a given key. You can perform the following operations on maps. You can test if...

JAVA please Arrays are a very powerful data structure with which you must become very familiar. Arrays hold more than one object. The objects must be of the same type. If the array is an integer array then all the objects in the array must be integers. The object in the array is associated with an integer index which can be used to locate the object. The first object of the array has index 0. There are many problems where...
