function that adds 1 to a counter when the method is called

Here's a simple example of a class in Java that has a method to increment a counter: ```java public class Counter { private int count; public Counter() { this.count = 0; } public void increment() { this.count++; } public int getCount() { return this.count; } public static void main(String[] args) { Counter counter = new Counter(); System.out.println("Initial count: " + counter.getCount()); counter.increment(); System.out.println("Count after increment: " + counter.getCount()); counter.increment(); System.out.println("Count after second increment: " + counter.getCount()); } } ``` In this example, the `Counter` class has a private integer field `count` to store the current count. The `increment` method increments the count by 1. The `getCount` method returns the current count. When you run this code, it will output: ``` Initial count: 0 Count after increment: 1 Count after second increment: 2 ``` This demonstrates that the `increment` method is working correctly and incrementing the counter each time it's called.

make a get API with response "Test"."Test" word should come from mysql DB and Admin portal should also be there which should be linked with DB to change the word and host on heroku or any Hosting site.

// This is a "stub" file. It's a little start on your solution. // It's not a complete solution though; you have to write some code. // Package greeting should have a package comment that summarizes what it's about. // https://golang.org/doc/effective_go.html#commentary package greeting // HelloWorld needs a comment documenting it as package does. func HelloWorld() string { return "Hello, World!" }
