Question

Write a method named hopscotch that accepts an integer parameter for a number of "hops" and prints a hopscotch board of that many hops. A "hop" is defined as the split into two numbers and then back together again into one. For example, hopscotch(3); should print ________.

Answer 1

Answer:

Following are the program in the Java Programming Language.

public class Main // declared class  

{

public void hopscotch(int x) // function definition  

{

int count=0; // variable declaration  

for (int j=0; j<x; j++) // iterating over the loop

{

System.out.println(" " + (++count)); // print the value of count

System.out.println((++count) + " " + (++count));

}

System.out.println(" " + (++count));  

}

public static void main(String[] args) // main method  

{

Main ob=new Main(); // creating object

ob.hopscotch(3); // calling hopscotch method  

}

}

Output:

  1

2     3

  4

5     6

  7

8     9

  10

Explanation:

Here, we define a class "Main" and inside the class, we define a function  "hopscotch()" and pass an integer type argument in its parentheses and inside the function.

• We set an integer variable "count" and assign value to 0.
• Set the for loop which starts from 0 and end at "x" then, print space and value inside the loop, again print value then space then value, then repeat the 1st print space then value.
• Finally, set the main function "main()" and inside the main function, we create the object of the class "ob" then, call the function " hopscotch()" through the object and pass the value 3 in its parentheses.
