Question

would someone kindly convert the following C code to java? thanks so much

# include <stdio.h>


int main(void)
{
    int changeOwed;
    int check;
    char invisibleChar;
    int count = 0;
        int numQ=0, numD=0, numN=0, numP=0;
    
    
    do{
          printf("How much change is owed (in cents)?\n");
        check = scanf("%d", &changeOwed); // returns 1 if the input is a number and returns 0 otherwise
        
        //Get's rid of any extra invisible characters if the input is a char/String
        do{
            scanf("%c",&invisibleChar);
        }while(invisibleChar != '\n');
            
    }while(check == 0 || !(changeOwed >=0 ));
    
    
        while(changeOwed > 0){
        
            //Use as many quarters needed
                while(changeOwed >= 25){
                        count ++;
                        numQ++;
                        changeOwed = changeOwed - 25;
                }
                //Use as many dimes needed
                while(changeOwed >= 10){
                        count ++;
                        numD++;
                        changeOwed = changeOwed - 10;
                }
                //Use as many nickels needed
                while(changeOwed >= 5){
                        count ++;
                        numN++;
                        changeOwed = changeOwed - 5;
                }
                //Use as many pennies needed
                while(changeOwed >= 1){
                        count ++;
                        numP++;
                changeOwed = changeOwed - 1;
                }

        }
    
        printf("Quarters: %d, Dimes: %d, Nickels: %d, Pennies: %d\nNumber of coins used= %d\n\n", numQ, numD, numN, numP, count);
}

Ans:- Java code for the following c code.

import java.util.*;
public class Cent
{
        //this function is used to check whether the input is integer or not 
        private static boolean checkInt(String x){
        int y;
        try{
            y = Integer.parseInt(x);
            return false;
            }catch(NumberFormatException ex){
                return true;
            }
        }
        public static void main (String[] args) 
        {
        int changeOwed=0;
        String c;        
        boolean check;
        int count = 0;
        Scanner obj = new Scanner(System.in); //Scanner class is used to take input in java
        int numQ=0, numD=0, numN=0, numP=0; 
        // it will run until user enter an integer       
        do{

            System.out.print("How much change is owed (in cents)?");
            c=obj.next(); //this statement will take input from user
            check=checkInt(c); //check whether the input is integer or not
          }while(check);
        changeOwed=Integer.parseInt(c);       
        while(changeOwed > 0){ //this while loop remain same in java
        
            //Use as many quarters needed
            while(changeOwed >= 25){
                count ++;
                numQ++; 
                changeOwed = changeOwed - 25;
            }
            //Use as many dimes needed
            while(changeOwed >= 10){
                count ++;
                numD++;
                changeOwed = changeOwed - 10;
            }
            //Use as many nickels needed
            while(changeOwed >= 5){
                count ++;
                numN++;
                changeOwed = changeOwed - 5;
            }
            //Use as many pennies needed
            while(changeOwed >= 1){
                count ++;
                numP++;
                changeOwed = changeOwed - 1;
            }

        }
        // the below statements are used to print the output
        System.out.println("Quarters: "+numQ+", Dimes: "+numD+", Pennies: "+numP);
        System.out.println("Number of coins used= "+count);
        }
}

Output:-
