How to Match an Array Against a String in Java?

How can I compare an array of strings to see if any match a specific string in Java?

String[] words = {"apple", "banana", "cherry"};
String target = "banana";

In Java, you can match an array of strings against a specific string using loops or built-in functions. This is especially useful for searching through a collection of items to find a specific one.

String[] words = {"apple", "banana", "cherry"};
String target = "banana";
boolean found = false;
for (String word : words) {
    if (word.equals(target)) {
        found = true;
        break;
    }
}
System.out.println("Found: " + found);

Causes

• Using the wrong data type for comparison (e.g., comparing a string and an integer).
• Incorrectly managing string case sensitivity between the array and the string.

Solutions

• Use a loop to iterate through the array and check if each element matches the string.
• Leverage Java's built-in methods like 'Arrays.asList()' combined with 'contains()' for cleaner code.

Mistake: Using '==' operator instead of '.equals()' for string comparison.

Solution: Always use '.equals()' method for comparing strings in Java to avoid reference comparison.

Mistake: Ignoring case sensitivity in arrays when matching to a string.

Solution: Use 'word.equalsIgnoreCase(target)' to perform case-insensitive matching.
