Here is a simple Java program that meets your requirements:

```java
public class MiniCalculator {
private double num1;
private double num2;

public MiniCalculator(double num1, double num2) {
this.num1 = num1;
this.num2 = num2;
}

public double sum() {
return this.num1 + this.num2;
}

public double product() {
return this.num1 * this.num2;
}

public double difference() {
return this.num1 - this.num2;
}

public double quotient() {
if (this.num2 != 0) {
return this.num1 / this.num2;
} else {
throw new IllegalArgumentException("Division by zero is not allowed.");
}
}
}

public class Test {
public static void main(String[] args) {
MiniCalculator calculator = new MiniCalculator(34.567, 234.54);
System.out.println("Sum: " + calculator.sum());
System.out.println("Product: " + calculator.product());
System.out.println("Difference: " + calculator.difference());
System.out.println("Quotient: " + calculator.quotient());
}
}
```

This program defines a `MiniCalculator` class with methods for sum, product, difference, and quotient. It then creates a `Test` class with a `main` method that creates an instance of `MiniCalculator` and uses it to perform calculations. The results are then printed to the console.

Here is a simple Java program that meets your requirements:

```java
public class MiniCalculator {
    private double num1;
    private double num2;

public MiniCalculator(double num1, double num2) {
        this.num1 = num1;
        this.num2 = num2;
    }

public double sum() {
        return this.num1 + this.num2;
    }

public double product() {
        return this.num1 * this.num2;
    }

public double difference() {
        return this.num1 - this.num2;
    }

public double quotient() {
        if (this.num2 != 0) {
            return this.num1 / this.num2;
        } else {
            throw new IllegalArgumentException("Division by zero is not allowed.");
        }
    }
}

public class Test {
    public static void main(String[] args) {
        MiniCalculator calculator = new MiniCalculator(34.567, 234.54);
        System.out.println("Sum: " + calculator.sum());
        System.out.println("Product: " + calculator.product());
        System.out.println("Difference: " + calculator.difference());
        System.out.println("Quotient: " + calculator.quotient());
    }
}
```

This program defines a `MiniCalculator` class with methods for sum, product, difference, and quotient. It then creates a `Test` class with a `main` method that creates an instance of `MiniCalculator` and uses it to perform calculations. The results are then printed to the console.
