Making my character jump

hxppy

I want to make my character jump using the letter 'W' any ideas?

Here's my code:

PImage back;
PImage back2;

boolean start = true;
boolean finish = false;
boolean scrolling = true;

boolean startGame;

Character mickey;
int b=0;

void setup() 
{
  size(700, 438);
  mickey = new Character();

  back = loadImage("back.png");
  back2 = loadImage("back2.png");
}

void draw() {
  image(back, b, 0);
  image(back2, b+width, 0);
  if (scrolling == true) {
    scroll();
  }

  if (startGame == false) {
    startScreen();
  }


  mickey.display();
  mickey.move();
}

void scroll() {
  b=b-1;
  if (b<-1*width) {
    b=0;
  }
}

void startScreen() {
  noFill();
  stroke(255);
  textSize(32);
  if (finish) {
    rect(20, 20, 100, 50);
  } else {
    rect(15, 40, 670, 50);
    rect(250, 370, 200, 50);


    if (start) {
      text("HELP MICKEY MOUSE FIND HIS FRIENDS", 50, 77);
      text("PLAY", 310, 405);
    } else {
      text("RETRY", 170, 140);
    }
  }
}

void keyPressed () {
  scroll();
  if (keyPressed) {
    if (key == 'd' || key == 'D') {
    }
  }
}

void mousePressed() {

  if (startGame == false) {
    if (mouseX>250 && 450>mouseX && mouseY>370 && 420>mouseY ) {
      scrolling=false;
      startGame = true;
    } else {
      scrolling=true;
    }
  }
}

and my class:

public class Character {

  PImage mickey;
  int rad; // Width of the shape
  float xpos, ypos;  // Starting position of shape  
  int xdirection, ydirection;  // Left or Right
  int xspeed, yspeed; // Speed of the character

  public Character() {
    mickey = loadImage("mickey.gif"); //this image is in data folder
    rad = 170; 
    xpos = 200;
    ypos = 200;
    xdirection = 0;
    ydirection = 20;
  }  
  public void display () {
    image(mickey, rad, rad, xpos, ypos);
  }
  public void move() {
    // Update the position of the shape
    xpos = xpos + ( xspeed * xdirection );
    ypos = ypos + ( yspeed * ydirection );
  }
}
