This problem is asking you to create a program that demonstrates the concept of method overloading in Java. Method overloading is a feature in Java that allows a class to have more than one method having the same name, if their argument lists are different.

Here is a step-by-step solution:

Step 1: Define a class, let's call it `Addition`.

```java
public class Addition {
}
```

Step 2: Inside the `Addition` class, create three `add()` methods.

- The first `add()` method should take two integers as parameters and return their sum.
- The second `add()` method should take two doubles as parameters and return their sum.
- The third `add()` method should take three integers as parameters and return their sum.

```java
public class Addition {
public int add(int a, int b) {
return a + b;
}

public double add(double a, double b) {
return a + b;
}

public int add(int a, int b, int c) {
return a + b + c;
}
}
```

Step 3: Now, create a `main()` method to test the `add()` methods.

```java
public class Addition {
public int add(int a, int b) {
return a + b;
}

public double add(double a, double b) {
return a + b;
}

public int add(int a, int b, int c) {
return a + b + c;
}

public static void main(String[] args) {
Addition addition = new Addition();

System.out.println("Sum of integers: " + addition.add(2, 3));
System.out.println("Sum of doubles: " + addition.add(0.67, 1.98));
System.out.println("Sum of three integers: " + addition.add(4, 9, 18));
}
}
```

When you run this program, it will print:

```
Sum of integers: 5
Sum of doubles: 2.65
Sum of three integers: 31
```

This is exactly what the problem is asking for.
