Answer:
d. public myClass( ) {. . .}
Explanation:
A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.
Having said these about a constructor, a few other things are worth to be noted by a constructor.
i. In Java, a constructor has the same name as the name of its class.
For example, in the given class <em>myClass</em>, the constructor(s) should also have the name <em>myClass</em>.
ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:
<em>public void myClass(){...}</em>
This makes option a incorrect.
iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.
This makes option d a correct option.
Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.
Answer:
I believe it is "Know what you are looking for and carefully filter information for accuracy."
Answer:
public class Main
{
public static void main(String[] args) {
System.out.println(starString(4));
}
public static String starString(int n){
double p = Math.pow(2,n);
String s = "";
for(int i=0; i<p; i++)
s += "*";
return s;
}
}
Explanation:
Create a method named starString that takes an integer parameter, n
Get the 2 to the nth power using pow method and set it to the p
Create an empty string that will hold the asterisks
Create a for loop that will iterate p times. Inside the loop, concatenate an asterisk to the s
Return the s
Inside the main method, call the method with an integer parameter
