Instructions This  assignment will help students understand interface implementation as a  crucial software engineering component. You will implement the given  interface in JAVA. Overall interface coding This assignment requires you  to write the Utilities211Code.java class which implements the  Utilities211Interface.java interface shown below. After you have written  the code for the Utilities211Code.java program, you will then test your  code with the Utilities211Driver.java code that I provide for you at  the end of the page. The expected results are at the bottom of the page  as well. Each of the methods properly implemented Overall coding  practices, comments, following the ICS Java coding standard, correct  results printed. Utilfties211Interface: abstract interface Utilities 211 Interface /*  Method reads a string and verifies that the string contains at least 2  non-blank characters. For example if the String is " a b " the string  length is 7 and the method returns true " x " the string length is 8 and the method returns false "" the string length is 0 and the method returns false "   " the string length is 12 and the method returns false "123abc" the  string length is 6 and the method returns true Just pointing out that  the length of the string doesn't determine the validity of the string.  @param String s the string to be tested @return boolean valid = true,  false otherwise */ abstract boolean validString(String s); /* @param  double d number to be tested @returnint 1 of the number is positive −1  of the number is negative 0 of the number is zero */ abstract int  numberSign(double d); /* This method receives 2 int numbers and counts  the numbers in range between them For example if int 1=20 and int 2=33 it will return 13 if int 1=12 and int 2=−5  it will return 17 @param int1, int2, numbers defining the range @return  int, range */ abstract int range(int i1, int i2); } Utilities211Driver.java. Use it to test your code. public class  Utilities211Driver{ public static void main(String[ ] arg)র double d=−2.1 int x=5; int y=−6; String s1= " x "; String s2=  " cow "; Utilities211Code u = new Utilities211Code( );  System.out.printIn(u.validString(s1));  System.out.println(u.validString(s2)); System.out.println(u.numberSign( d  )); System.out.println(u.range( (x,y) ); } } Your output when running this program should be:

Please provide assistance in writing a Code that will implement Utilities211Interface and Utilities211Driver. Thank you
