Multi-texturing java opengl

I would like display more than one texture in screen. I’m working on OpenGl JAVA. Code Example:

gl.glEnable(GL2.GL_TEXTURE_2D); //carga texturas:      
       try {
    	  File in = new File("mariosprite1.png");
    	   InputStream stream = getClass().getResourceAsStream("mariosprite1.png");
    	   TextureData data = TextureIO.newTextureData(gl.getGLProfile(),in, GL2.GL_RGBA16, GL2.GL_RGBA, false, "png");
    	   t = TextureIO.newTexture(data);
       }catch(IOException e) {
    	   e.printStackTrace();
    	   System.exit(1);
       }
      try {
      File in3 = new File("goomba.png");
      InputStream stream3 = getClass().getResourceAsStream("goomba.png");
      TextureData data3 = TextureIO.newTextureData(gl.getGLProfile(),in3, GL2.GL_RGBA16, GL2.GL_RGBA, false, "png");*/
      t3 = TextureIO.newTexture(data3);
      }catch(IOException e) {
	      e.printStackTrace();
	      System.exit(2);
     }

The second texture isn’t being displayed, why?
