Show String in Oval
This section illustrates you how to show the string in Oval.
To show a string in oval, we are providing you an example. A font 'Book Antiqua' is defined to display the string 'WELCOME'.
To render the
particular font on the screen, we have used the class FontMetrics. The object
of FontMetrics class encapsulates all the information.
The method drawOval() draw
an oval shape. The char ch = st.charAt(k) retrieves the k character
on each iteration. The method getHeight() of class FontMetrics gets the
standard height of a line of text in the given font. The method charWidth(ch) of
class FontMetrics returns the width of the specified character in the given
font.
Following code draws the string in oval:
| g.drawString(String.valueOf(ch), x, y + h); |
Here is the code of ShowFontInOval.java
import java.awt.*;
import javax.swing.*;
public class ShowFontInOval extends JPanel {
public void paint(Graphics g) {
g.setFont(new Font("Book Antiqua",0,90));
g.setColor(Color.cyan);
FontMetrics fontMetrics = getFontMetrics(new Font
("Book Antiqua",0,90));
String st = "WELCOME";
int x = 1;
int y = 1;
for (int k = 0; k < st.length(); k++) {
char ch = st.charAt(k);
int h = fontMetrics.getHeight();
int w = fontMetrics.charWidth(ch);
g.drawOval(x, y, w, h);
g.drawString(String.valueOf(ch), x, y + h);
x= x + w;
}
}
public static void main(String[] args) {
JFrame f = new JFrame("Show string in Oval");
f.setContentPane(new ShowFontInOval());
f.setSize(520, 300);
f.setVisible(true);
}
}
