Answer:
The right answer is option 2: instance variables and their values
Explanation:
Let us define what an object is.
An object is a blueprint of a real-world identity. The instances are the reference to the object. Multiple instances of an object type can be made.
The instance variables and their values help us to determine the state of the object.
Hence,
The right answer is option 2: instance variables and their values
COMPLETE QUESTION
I. public class Test {
public static void main(String[] args){
System.out.println("Welcome to Java!");
}
}
II. public class Test { public static void main(String[] args) {System.out.println("Welcome to Java!");}}
Answer:
Both codes will compile and run and display Welcome to Java, but the code in II has a better style than I
Explanation:
When written codes, paying attention to proper coding styles and efficient memory management enables us to create programs that are highly efficient, coding styles refer to proper indentions and avoiding too lenghty lines of code (as is in code I), adding approprite comments etc.
Here is my solution. I did the following:
- changed the setRemover into a constructor, since the comment seems to hint that that is expected.
- changed the lookFor type into a String, so that it can work with the string replace overload. That's convenient if you want to replace with an emtpy string. The char type won't let you do that, you can then only replace one char with another.
- Added a static Main routine to use the class.
import java.lang.System.*;
public class LetterRemover
{
private String sentence;
private String lookFor;
public LetterRemover() {}
// Constructor
public LetterRemover(String s, char rem)
{
sentence = s;
lookFor = String.valueOf(rem);
}
public String removeLetters()
{
String cleaned = sentence.replace(lookFor, "");
return cleaned;
}
public String toString()
{
return sentence + " - letter to remove " + lookFor;
}
public static void main(String[] args)
{
LetterRemover lr = new LetterRemover("This is the tester line.", 'e');
System.out.println(lr.toString());
String result = lr.removeLetters();
System.out.println("Resulting string: "+result);
}
}

Answer:
= B9 + B10 - E8
Explanation:
Required
Create a formula in E10 that subtracts E8 from the sum of B9 and B10
The sum of B9 and B10 is represented with B9 + B10
When E8 is subtracted, the formula becomes B9 + B10 - E8
To write a formula in Excel, you start with " = " sign.
So, type the following in cell E10
<em>= B9 + B10 - E8</em>
<em />
<em>The cell references in this case are the name of the cells; i.e. B9, B10 and E8</em>
