Answer:
The correct answer for the given question is   "Machine languages can be used to write programs that can run on any machine."
Explanation:
The machine language consist of binary digit i. e 0 and 1 .Computer can understand only the machine language .The machine language consist of code that is written in bits so it is used  to express algorithms.When any program is compiled the compiler are converted into machine code so the machine language is produced by the compiler .
Machine language cannot used to write a program that run on any machine.

By default, if you do not implement a constructor, the compiler will use an empty constructor (no parameters and no code). The following code will create an instance of the MyObject class using the default constructor. The object will have the default vauesfor all the attributes since no parameters were given. 
MyObject obj = new MyObject();
Another type of constructor is one with no parameters (no-arg constructor). It is similar to the default, except you actually create this constructor. The contents of the the constructor may include anything. To call a no-arg constructor, use the same line of code as above. The constructor can look like the one below:
public MyObject() {
System.out.println("This is a no-arg constructor");
}
Lastly there is the parameterized constructor. This type of constructor takes in parameters as inputs to assign to values in the newly created object. You call a parameterized constructor as follows:
MyObject obj = new MyObject("Bob", 20);
The constructor will look like this:
public MyObject(String name, int age) {
this.name = name;
this.age = age;
}
In the constructor, the keyword "this" refers to the object, so this.name is a private global variable that is being set equal to the inputted value for name, in this case "Bob".
Hope this helps!
        
             
        
        
        
Answer:
The answers are explained below
Explanation:
1) Identify the potential classes in this problem domain be list all the nouns
class Customer
class Acco  unt
2) Refine the list to include only the necessary class names for this problem
the class customer is not necessary to solve the problem itself, therefore the only class could be the account class
3) Identify the responsibilities of the class or classes.
The responsibilities of the class account will be
* determination of the type of account--> Acc  ount . type(char)
*  deposit money into the account --> Acc  ount . de posit(float)
* withdraw money into the account --> Acc  ount . with draw(float)
* show balance of the account --> Acc  ount . bal ance()
* generate interest --> Acc  ount . int erest()
Please join the words together. I used spaces due to regulations
 
        
             
        
        
        
Answer:
<h2>A negative impact.</h2>
Explanation:
The unemployed are also unable to purchase as many goods, so will contribute to lower spending and lower output. A rise in unemployment can cause a negative multiplier effect.
