    Default How to the main method for this class

    Can somebody help me with the main method of this.


    import java.awt.*;
    import java.awt.geom.*;

    public class WobbleStroke implements Stroke {

    private float detail = 2;
    private float amplitude = 2;
    private static final float FLATNESS = 1;


    public WobbleStroke( float detail, float amplitude ) {
    this.detail = detail;
    this.amplitude = amplitude;
    }

    public Shape createStrokedShape( Shape shape ) {
    GeneralPath result = new GeneralPath();
    shape = new BasicStroke( 10 ).createStrokedShape( shape );
    PathIterator it = new FlatteningPathIterator( shape.getPathIterator( null ), FLATNESS );
    float points[] = new float[6];
    float moveX = 0, moveY = 0;
    float lastX = 0, lastY = 0;
    float thisX = 0, thisY = 0;
    int type = 0;
    boolean first = false;
    float next = 0;

    while ( !it.isDone() ) {
    type = it.currentSegment( points );
    switch( type ){
    case PathIterator.SEG_MOVETO:
    moveX = lastX = randomize( points[0] );
    moveY = lastY = randomize( points[1] );
    result.moveTo( moveX, moveY );
    first = true;
    next = 0;
    break;

    case PathIterator.SEG_CLOSE:
    points[0] = moveX;
    points[1] = moveY;
    // Fall into....

    case PathIterator.SEG_LINETO:
    thisX = randomize( points[0] );
    thisY = randomize( points[1] );
    float dx = thisX-lastX;
    float dy = thisY-lastY;
    float distance = (float)Math.sqrt( dx*dx + dy*dy );
    if ( distance >= next ) {
    float r = 1.0f/distance;
    float angle = (float)Math.atan2( dy, dx );
    while ( distance >= next ) {
    float x = lastX + next*dx*r;
    float y = lastY + next*dy*r;
    result.lineTo( randomize( x ), randomize( y ) );
    next += detail;
    }
    }
    next -= distance;
    first = false;
    lastX = thisX;
    lastY = thisY;
    break;
    }
    it.next();
    }

    return result;
    }

    private float randomize( float x ) {
    return x+(float)Math.random()*amplitude*2-1;
    }

    }

    help me with the main method
    Please explain what the main method is supposed to do. Be specific and give details.

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE HERE
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
