Screen resolution can be obtained through a Java program by using Toolkit.getScreenSize() method. getScreenSize() is a method of the java Toolkit class of java.awt package. It gets the size of the screen. On systems with multiple displays, the primary display screen resolution is returned.
- Dimension size = Toolkit.getDefaultToolkit().getScreenSize();
- getScreenSize will return the size in pixel.
- If directly size is printed, then it is displayed in the format: java.awt.Dimension[width=1366, height=768]
Declaration
public abstract Dimension getScreenSize()
Returns: The size of the current screen in pixels
Exception
HeadlessException (if GraphicsEnvironment.isHeadless() returns true)
Java
// Java code to display the screen sizeimport java.awt.*; class GFG { public static void main(String[] args) { // getScreenSize() returns the size // of the screen in pixels Dimension size = Toolkit.getDefaultToolkit().getScreenSize(); // width will store the width of the screen int width = (int)size.getWidth(); // height will store the height of the screen int height = (int)size.getHeight(); System.out.println("Current Screen resolution : " + "width : " + width + " height : " + height); }} |
