Introduction to 'public static void setPointSize' function

The setPointSize function is a public static method in Java that allows programmers to set the point size for a text object in a graphical user interface (GUI) application.

Syntax

The syntax for the setPointSize function is as follows:

public static void setPointSize(float pointSize);

Parameters

The setPointSize function takes a single parameter, pointSize, which is the size of the text in points.

Return Value

The setPointSize function does not return a value, as it sets the point size for a text object in the GUI application.

Usage

Below is an example usage of the setPointSize function:

import javafx.scene.text.Font;

public class Main {
    public static void main(String[] args) {
        Font font = new Font("Arial", 12);
        font = Font.font(font.getFamily(), FontWeight.BOLD, 16);
        Font.setPointSize(24f);
        System.out.println(font.getSize());
    }
}

In this example, we import the Font class from the JavaFX library, create a new Font object with a size of 12 points, and then create a new Font object with a size of 16 points and a bold weight. We then call the setPointSize function with a size of 24 points, and print the size of the font object (which should be 24).

Conclusion

The setPointSize function is a useful method for controlling the size of text in a GUI application. By specifying the size of the text in points, programmers can create text that is easy to read and visually appealing.
