Write a function that takes an integer array and replaces all the odd numbers with the next greater even number.

public class EvenNumbers { public static void main(String[] args) { int i = 2; while (i <= 10) { System.out.println(i); i += 2; } } } Output: 2,4,6,8,10 **EXAMPLE2:** public class ReverseEvenNumbers { public static void main(String[] args) { int i = 10; while (i >= 2) { System.out.println(i); i -= 2; } } } Output: 10,8,6,4,2 **Example3:** package While; public class RverseMultipleThree { public static void main(String[] args) { int i = 15; while (i >= 3) { System.out.println(i); i -= 3; } } } Output: 15,12,9,6,3 **Example4:** package While; public class MutipleThree { public static void main(String[] args) { int i = 3; while (i <= 15) { System.out.println(i); i += 3; } } } Output: 3,6,9,12,15 **Example5:** package While; public class Number { public static void main(String[] args) { int a = 7; int b = 10; while (a <= 10 && b <= 13) { System.out.print(a + "," + b); if (a < 10 && b < 13) { System.out.print(","); } a = a + 1; b = b + 1; } } } Output: 7,10,8,11,9,12,10,13 **Example6:** package While; public class Number2 { public static void main(String[] args) { int a = 10; while (a <= 50) { System.out.print(a); if (a < 50) { System.out.print(","); } a += 10; } } } Output: 10,20,30,40,50 **Example7:** package While; public class Number3 { public static void main(String[] args) { int a = 90; while (a >= 15) { System.out.print(a); if (a > 15) { System.out.print(","); } a -= 15; } } } Output: 90,75,60,45,30,15 **Example8:** package While; public class Number4 { public static void main(String[] args) { int a = 36; while (a >= 24) { if (a != 32 && a != 26) { // Skip 32 and 26 System.out.print(a); if (a > 24) { System.out.print(","); } } a -= 2; } } } Output: 36,34,30,28,24
