Lab 3 - Loops, Strings, and Arrays Exercise 1 Create a file named A3.java. Place all your code this file. Create a method with the following header: public static boolean endOther(String a, String b) Define it as follows: Given two strings, return true if either of the strings appears at the very end of the other string, ignoring upper/lower case differences in other words, the computation should not be "case sensitive"). Note: str.to LowerCase() returns the lowercase version of a string. endOther("Hiabc", "abc") true endOther("AbC", "HiaBc") true endOther("abc", "abXabc") true Exercise 2 Create a method with the following header: public static int sum13(int[] nums) Define it as follows: Return the sum of the numbers in the array, returning 0 for an empty array. Except the number 13 is very unlucky, so it does not count and numbers that come immediately after a 13 also do not count. sum13([1, 2, 2, 1]) 6 sum13([1,1]) 2 sum13([1, 2, 2, 1, 13]) 6
