Question

Question 1 Consider the method	displayRowOfCharacters	that displays any
given character the specified number of times on one line. For example, the call:

displayRowOfCharacters('*', 5);

produces the line: *****
Implement this method in Java by using recursion.

Question 2

Write a method that asks the user for integer input that is between 1 and 10, inclusive. If the input is out of range, the method should recursively ask the user to enter a new input value.

HELP ME PLEASE.

Answer 1

Question 1

Raw code:

//class name

class Main {

//main

public static void main(String[] args) {

//calling static method

displayRowOfCharacters('*', 5);

}

//method to display characters s of count k

public static void displayRowOfCharacters(char s,int k) {

//codition to reutrn nothing when k is 0

if (k ==0) {

return ;

}

//if k is greater than 0

else {

//print the characters

System.out.print(s);

//call the function recursively

displayRowOfCharacters(s, k-1);

}

}

}

Question 2

Raw code:

import java.util.Scanner;

//class name

class Main {

//main

public static void main(String[] args) {

//calling static method

ask_input();

}

//method to ask input between 1 and 10 inclusinve

public static int ask_input(){

//object to Scanner

Scanner sc = new Scanner(System.in);

//prompt

System.out.println("Entr value between 1 and 10 : ");

//get input from user

int input=sc.nextInt();

//checking input condition

if(input>=1 &&input<=10){

//if satisfied return input

return input;

}

//else recursively ask for the input

else{

System.out.print("Please enter between 1 and 10 ");

return ask_input();

}

}

}
