How do you print a dashed line in Java?

What does printing a line of dashes have to do with printing line breaks? You’re already printing a line break every time you call println() . If you want a blank line, which isn’t stated, just call println() with no arguments.

How to set Stroke in java?

To set the stroke attribute, you create a BasicStroke object and pass it into the Graphics2D setStroke method. A BasicStroke object holds information about the line width, join style, end-cap style, and dash style. This information is used when a Shape is rendered with the draw method.

What is BasicStroke in Java?

The BasicStroke class defines a basic set of rendering attributes for the outlines of graphics primitives, which are rendered with a Graphics2D object that has its Stroke attribute set to this BasicStroke . These rendering attributes include: width. The pen width, measured perpendicularly to the pen trajectory.

What is fillRect in Java?

fillRect. public abstract void fillRect(int x, int y, int width, int height) Fills the specified rectangle. The left and right edges of the rectangle are at x and x + width – 1 . The top and bottom edges are at y and y + height – 1 .

How do you create a line break in Java?

In Windows, a new line is denoted using “\r\n”, sometimes called a Carriage Return and Line Feed, or CRLF. Adding a new line in Java is as simple as including “\n” , “\r”, or “\r\n” at the end of our string.

How do you repeat a char in Java?

Here is the shortest version (Java 1.5+ required): repeated = new String(new char[n]). replace(“\0”, s); Where n is the number of times you want to repeat the string and s is the string to repeat.

How do you draw a line in Java?

Java Applet | Draw a line using drawLine() method

  1. x1 – It takes the first point’s x coordinate.
  2. y1 – It takes first point’s y coordinate.
  3. x2 – It takes second point’s x coordinate.
  4. y2 – It takes second point’s y coordinate.

How do you draw an arc in Java?

Draw Arc in Java Applet

  1. import java. awt.*;
  2. import java. applet.*;
  3. public class Mouth extends Applet.
  4. {
  5. public void paint (Graphics g)
  6. {
  7. g. drawArc(60, 125, 80, 40, 180, 180); // Draw an Arc Shape.
  8. g. fillArc(60, 125, 80, 40, 180, 180); // Fill an Arc Shape.

How to draw a dashed line in Java?

To draw a dashed line, specify a dashing pattern when creating the stroke. For example: This pattern specifies that the first two pixels are opaque; the next two are transparent; the next two are opaque; and so on…. Here’s the result: The original example is updated to draw dashed lines as follows:

How to apply a stroke to a shape in Java?

To add this stroke to the Graphics2D context before you render the line call the setStroke method. Similarly, you apply a gradient fill to a Shape object by creating a GradientPaint object and adding it to the Graphics2D context. The following code lines enrich geometric primitives with filling and stroking context:

How is the dash style defined in Java?

The dash style is defined by a dash array and a dash phase. The dash array defines the dash pattern. Alternating elements in the array represent the dash length and the length of the space between dashes in user coordinate units.

How does the dash array work in Java?

The dash array defines the dash pattern. Alternating elements in the array represent the dash length and the length of the space between dashes in user coordinate units. Element 0 represents the first dash, element 1 the first space, and so on. The dash phase is an offset into the dash pattern, also specified in user coordinate units.
