Question

Consider the following code, which is a portion of SomeClass. The instance variable is initialized by the constructor. The method is supposed to multiply the value passed as a parameter by the instance variable and update the value of the instance variable. However, there is a problem. Re-write this code, without renaming any variable names, to resolve the problem.

private int number;

public void multiplyNumbers(int number)

{

number = number * number;

System. Out. Println("The local variable is: " + number);

System. Out. Println("The instance variable is: " + number);

}

Answer 1

Use the knowledge of computational language in JAVA to write a code which is a portion of SomeClass.

To make it simpler the code is described as:

SomeClass

private int number;

public void subtractNumbers(int number)

{

   number = number − number;

   System.out.println("The local variable is: " + number);

   System.out.println("The instance variable is: " + number);

}

Answer 2

Answer:

Correct code (For everyone confused):

private int number;

public void multiplyNumbers(int number) {

 this.number = this.number * number;
 System.out.println("The local variable is: " + number);
 System.out.println("The instance variable is: " + this.number);

}

Explanation:

the this. command allows the instance variable of the class to be called instead of the variable in the constructor which as shown can stay the same while still changing the instance variable of the same name. Allowing for the code to be, say if int number was 5. Then the instance variable would be, 5 + 5, which would print:

The local variable is: 5
The instance variable is: 10
