Searching for a String in an Array and returning the position
Hi I'm a complete newbie on programming and I try to search for a certain String in an array. When it's found the method should return the index but if the String is not found it should return -1.
public int poitionOfWord(String testWord) {
for (int i = 0; i < wordArray.length; i++) {
if (wordArray[i].equals(testWord)) {
return i;
}
}
return -1;
}
would this method return always -1 or would it actually terminate when finding a word and would return i.
java arrays equals

It will terminate as soon as there's a match, i.e. it will short-circuit.

You have to make sure the content oftestWordis actually stored inwordArrayon an arbitrary position. Otherwise, you code looks ok and should meet the requirements.

Your code is fine. It will return the position of the item if found or -1 if not found.

Your method is correct and it will return the index in case it finds a match else if it doesn't find the match, it will come out of loop and return -1.
Just to make code crisp and concise, you can use something like this,
public static String wordArray = new String{"a", "b"};
public static int poitionOfWord(String testWord) {
return Arrays.asList(wordArray).indexOf(testWord);
}
Then test it with some code,
public static void main(String args) {
System.out.println(poitionOfWord("a"));
System.out.println(poitionOfWord("z"));
}
This prints,
1
-1
