To create a color object with specific components and opacity, you can use the Color class in Java:
```java
Color color = new Color(red, green, blue, alpha);
```
Here, `red`, `green`, `blue` are integers between 0 and 255 representing the RGB components of the color, and `alpha` is a float value between 0 and 1 representing the opacity of the color.
To create a Font object and set its properties, you can use the Font class in Java:
```java
Font font = new Font(name, style, size);
```
Here, `name` is a string representing the name of the font (e.g. "Helvetica"), `style` is an integer representing the style of the font (e.g. Font.BOLD), and `size` is an integer representing the size of the font in points. You can also set the font weight and posture using the `Font.deriveFont()` method:
```java
Font boldFont = font.deriveFont(Font.BOLD);
Font italicFont = font.deriveFont(Font.ITALIC);
```
These methods return a new Font object with the specified style.
