Fengbin: JavaFX Instance (12) "Colortext"

The following instance repeats a line of text in a different color and direction.

This example code is as follows:

import java.util.random; import javafx.application.application; import  javafx.scene.group; import javafx.scene.scene; import javafx.scene.paint.color;  import javafx.scene.text.text; import javafx.stage.stage;  public class  colortext extends application {     @Override  // override the  start method in the Application class        Public void start (stage primarystage)  {       group  root = new group ();        scene scene =  new scene (Root, 300, 250, color.white);        Random rand = new random (System.currenttimemillis ());        for  (int i=0; i<100; i++)  {          int x =  Rand.nextint ((int) scene.getwidth ());           int y  = rand.nextint ((int) scene.getheight ());             int red = rand.nextint (255);           int green = rand.nextint (255);           int blue = rand.nextint (255);            text text = new text (x,y,  "javafx programing  fengbin");            int rot = rand.nextint (;   )        text.setfill (Color.rgb (red,green, blue, .99));        &nbSp;  text.setrotate (Rot);           Root.getchildren (). Add (text);       }         primarystage.settitle ("Colortext");        primarystage.setscene (scene);        primarystage.show ();    }}

The results of the operation are as follows:

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/4E/72/wKioL1RgmD6iecPPAAHGpDLPbbM637.jpg "title=" Qq20141110171904.png "alt=" Wkiol1rgmd6iecppaahgpdlpbbm637.jpg "/>

Description

1.since The initial release of the JDK, we can use the java.util.Random class to generate random numbers. In JDK1.2 ,the Random class has a method named nextint () :

public int Nextint (int n)

Given a parameter n,nextint (n) returns a random number greater than or equal to 0 less than n , i.e.: 0<= nextint (n) < n .

2. System.currenttimemillis () It returns the number of milliseconds that have elapsed since UTC 1970 1 months , 1 days, and midnight.

3. The seed used by the new Random () construction method is the current system.currenttimemillis () ,so the above code:Random rand = new Random (System.currenttimemillis ()); can be shortened to Random rand = new Random ();

4. Group root = new Group (); can be changed into Pane Pane = new Pane ();
