Describe what problem occurs in the following code. What modifications should be made to it to eliminate the problem? int[] sums = {6, 12, 3, 32, 12, 10, 9, 6}; for (int index = 1; index <= sums.length; index += 1) { System.out.println(sums[index]); }
Write a program named Search.java that uses a function called search_string to check whether a string exists in the array or not. 1- The array of strings is iterated using a for loop and the value at every index is compared with the value to be searched in the array. 2- A boolean variable is set if any array value matches with the string. 3- At the end of the loop, this boolean variable is checked to determine if the array contains the string. Hint: You may need to import java.util.Arrays then use Arrays.toString, String equals(). The ouput should look like what is pictured below. Please provide an editable code that is easy to copy and paste.
