Why is my java method returning "-1" even if the string is in the array?
The method is:
public static int findWord(String wordToFind {
boolean found=false;
int i=0;
while
(i<words.length&& !found)
if (words[i]==wordToFind)
found=true;
else i++;
if (found)
return i;
else return -1;
}

JAVA 1.Write a static method named getMaxEven(numbers) which takes an array of positive integers as a parameter. This method calculates and returns the largest even number in the list. If there are no even numbers in the array, the method should return 0. You can assume that the array is not empty. For example: Test Result int[] values = {1, 4, 5, 9}; System.out.println(getMaxEven(values)); 4 System.out.println(getMaxEven(new int[]{1, 3, 5, 9})); 0 public static int --------------------------------------------------------------------------------- 2.

Write a method will accept an array of Strings. This method should return the string that comes after all the other strings in lexicographical order. (Assume all the Strings only contain lower case letters. In Example: No number, no Capitals and no Symbols) lastString({“hola”, “word”, “night”, “boom”}) → “word” lastString({“java”, “is”, “so”, “much”, “fun”}) → “so” lastString({“i”, “love”, “java”}) → “love” //precondition: words.length >0 public static String lastString(String[] words) { }

JAVA: Excerpt B.A: Complete the implementation of the following method. The purpose of this method is to return true if and only if all the elements in the array are x. In other words, all elements in the array are the value x (replace -a- with right answer). public static -a- allSame(int[] nums, int x){ for (int i = 0; i < -a-; i++){ if (nums[i] -a- x){ return -a-; } } return -a- } Excerpt B.B: What is printed...

The first file is an array based list. We have looked at node based implementations of both stacks and queues. An array based list utilizes an array of nodes to support common operations; note that the node class that we utilize has neither next nor previous references. Integer subscripts are maintained to keep track of both the front and rear. _____________________________________________________________________________________________________ class Node { private int key; public Node() { key = -1; } public Node(int k) { key =...

My program wont return boolean. There's nothing in the console.Here's the instructions: Given an array of ints, compute recursively if the array contains somewhere a value followed in the array by that value times 10. We'll use the convention of considering only the part of the array that begins at the given index.In this way, a recursive call can pass index+1 to move down the array. The initial call will pass in index as 0. examples are: array220([1,2,20],0)----true array220([3,30],0)----true array220([3],0))----false...
