Gavin, we can do it by creating a simple string type method. I hope you already know about java methods well. If not, you should learn, and practice it ASAP. Java is an OOP language, so learning the usages methods and objects is a must in java. It makes our program efficient and multi-functional alongside. 

Let’s write a program that works as like as you want:

public class HelloBob {
    public static void main(String[] args) {
        HelloBob test = new HelloBob();
        System.out.println(test.helloString("Bob"));
    }
    public String helloString(String input) {
        return "Hello " + input + "!";
    }
}

Keep exploring and solving problems.
Thanks
