Write a method with the following header to format the integerwith the specified width.public static String format(int number, int width)The method returns a string for the number with one or more prefix 0s. The size of thestring is the width. For example, format(34, 4) returns 0034 and format(34,5) returns 00034. If the number is longer than the width, the method returns thestring representation for the number. For example, format(34, 1) returns 34.Write a test program that prompts the user to enter a number and its width, anddisplays a string returned by invoking format(number, width).

Repeating String Write a method that takes a String and an int and return a String that is the original String repeated n times. For example, repeatString("Famous", 3) should return "FamousFamousFamous" The method signature should be public String repeatString(String str, int n)   public String repeatString(String str, int n) { //declare a string variable   //set up statements for repeating n number of times         //create the appropriate return statement   }

JAVA PPROGRAM ASAP   Please create  this program ASAP BECAUSE IT IS MY LAB ASSIGNMENT #2 so it passes all the test cases. The program must pass the test case when uploaded to Hypergrade.    Chapter 9. PC #8. 8. Sum of Numbers in a String (page 610) Write a program that asks the user to enter a series of numbers separated by commas. Here are two examples of valid input: 7,9,10,2,18,6 8.777,10.9,11,2.2,-18,6 The program should calculate and display the sum of all the numbers. Input Validation 1. Make sure the string only contains numbers and commas (valid symbols are '0'-'9', '-', '.', and ','). 2. If the string is empty, a messages should be displayed, saying that the string is empty.   Test Case 1     Enter a series of numbers separated only by commas or type QUIT to exit:\n7,9,10,2,18,6ENTERThe sum of those numbers is 52.00\nEnter a series of numbers separated only by commas or type QUIT to exit:\nENTEREmpty string.\nEnter a series of numbers separated only by…
