Write a method that accepts a String as an argument and returns an int array. Assume that the string contains a series of single digit numbers separated by a comma. (e.g. 2,3,4,5). The method should return an array with the smallest element in the string.Hint: To convert a character to a string use the static toString method in the Character class.

Program plan:

• Import the necessary header files.
• Define the class “Conversion”.
  • Define the method “small()” to find the smallest element in the string.
    • Initialize the array.
    • Split the string by comma using the method “split()” and store into an array.
    • Use “for” loop to convert the string into an integer array.
    • Use “for” loop to find and return the smallest element in an array.
  • Define the “main()” method.
    • Get the string from the user using “Scanner()” method.
    • Call the method “small()” to find the smallest element.
    • Use “for” loop to print the result.

Copyable code:

//Import the necessary header files
import java.util.*;

//Define the class
public class Conversion
{
//Define the method "small"
int[] small(String str)
{
//Initialize the array
int arr[]=null;

//Split the string
String a[]=str.split(",");

//Declare the array length
arr=new int[a.length];

//Loop to find the array length
for(int i=0;i<a.length;i++)

//Convert the string into an array
arr[i]=Integer.parseInt(a[i]);

//Initialize the minimum value
int min=999;

//Initialize the count
int count=0;

//For loop to find the smallest element
for(int i=0;i<arr.length;i++)
{
//Check the condition
if(min>arr[i])

//Assign the minimum value
min=arr[i];

}

//Loop to return the minimum value
for(int i=0;i<arr.length;i++)
{
//Check the condition
if(min==arr[i])

//Increment the count by 1
count++;
}

//Return the minimum value in an array
int r_arr[]=new int[count];
for(int i=0;i<count;i++)
r_arr[i]=min;
return r_arr;
}

//Define the "main()" function
public static void main(String[] args)
{
//Print the statement
System.out.println("Enter the string");

//Create object for "Scanner()" method
Scanner sc = new Scanner(System.in);

//Get the string from the user
String number = sc.nextLine();

//Object creation
Conversion con=new Conversion();

//Call the method "small()"
int a[]=con.small(number);

//Loop to print the result
for(int i=0;i<a.length;i++)
System.out.println(a[i]);
}
}
