Answer:
The output is "A"
Explanation:
public class Solution {
public static void main(String args[]) {
mystery(7);
}
public static void mystery(int a) { System.out.println("A"); }
public static void mystery(double a) { System.out.println("B"); }
public static void mystery(int a, double b) { System.out.println("C"); }
public static void mystery(double a, int b) { System.out.println("D"); }
}
In the code above; mystery is defined in four different ways called method overloading. Method overloading is when same method is defined with different parameters.
In the first case; mystery will be called if the argument is int.
In the second case; mystery will be called if the argument is double.
In the third case; mystery will be called if the arguments are int and double.
In the fourth case; mystery will be called if the arguments are double and int.
When mystery(7) is called; the mystery method requiring only int will be called and the output is "A".
Answer:
The following statement is False.
Explanation:
Because asper textbook there are only one main criteria against the test documents that find on the internet i.e., authorship. So, that's why the following given statement is false. The graphic and the interactivity depends on the quality of the document this options do not come under the criteria to test the document.
Answer:
Following are the code in the java language
numBers = scnr.nextInt ( ) ;
Here scnr is an instance of scanner class .
Explanation:
In this code, we take the input by using the object of Scanner class i.e "scnr". The scanner class in the java programming language is used for taking the input by the user. The scnr.nextInt ( ) is taking the input which is stored in the "numbers" variable.
So the whole program is looking like that
import java.util.*; // import package
public class Main
{
public static void main(String[] args) // main function
{
int numBers; // variable declaration
Scanner scnr=new Scanner(System.in); // create the instance of scanner class
numBers=scnr.nextInt( ) ; // taking input
System.out.println(numBers); // display the value of numBers
}
}
Output:
78
78
