This is a Java programWrite a method with the following header to format the integer with the specified width. public String format(int number, int width) The method returns a string for the number with one or more prefix 0s. The size of the string is the width within the range 1 to 10000inclusive. For example, format(34, 4) returns 0034 and format(34,5) returns 00034. If the number is longer than the width, the method returns the string representation for the number. For example, format(34, 1) returns 34. Assume that, the size of the string is the width within the range 1 to 10000 inclusive and the number is an integer -2147483648 to 2147483648 inclusive. Input 34 4Output 0034You must use this particular Driver classclass DriverMain{public static void main(String args[]){Scanner input = new Scanner(System. in);int num = Integer. parseInt(input. nextLine().trim());int width = Integer. parseInt(input. nextLine().trim());GW6_P5 gw6P5 = new GW6_P5();System. out. print(gw6P5.format(num, width));}

Following are the code to this question:

import java.util.*;//import package  

public class DriverMain//defining a class DriverMain

{

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

{

int num,width;

Scanner input = new Scanner(System.in);//creating Scanner class fore user input

num = Integer.parseInt(input.nextLine().trim());//input value

width = Integer.parseInt(input.nextLine().trim());//input value

GW6_P5 gw6P5 = new GW6_P5();//creating base class object

System.out.print(gw6P5.format(num,width));//print method that calls base class format method

}

}

class GW6_P5 //defining base class GW6_P5

{

String format(int number, int width)//defining method format that takes two integer variable in its parameter  

{

String s = ""+number;//defining s String variable that holdes integer value

int digitCount = 0;//defining integer variable

while(number!=0) //defining while loop to check value is not equal to 0

{

digitCount++;//incrementing the integer variable value

number/=10;//holding quotient value

}

if(width>digitCount)//defining if block that checks width value greather then digitCount value  

{

for(int i=0;i<width-digitCount;i++)//defining for loop to add 0 in String variable  

{

s = "0"+s;//add value

}

}

return s;//return String value

}

}

Output:

34

5

00034

Explanation:

In the given code, a class "DriverMain" is defined, and inside the class main method is defined that defines two integer variable "num and width", that uses the scanner class to input the value, and in the next step the "GW6_P5" class object is created that calls the format method and print its values.

In the class "GW6_P5", the format method is defined, that declared the string and integer variables, in the while loop it checks number value not equal to 0, and increments the number values, and in the for loop it adds the 0 in string value and return its value.
