I have the following question:

I have an array of 12 numbers (0 or 1) related to a list of buttons called "paisajeButtons[]". I need to program something that allows me to click only 5 and erase the first one when I click the 6th. 

I have an array of 5 positions in order called "clickOn[]"

From here everything is fine,

if I manually turn off one of the five button, it works at the first step, but it doesn't when I have the second unselect with 4 buttons on. 

I'm trying this but not going well:

1. for (int i = 0; i < 12; i++) {
       if (counterButtons > 0 ) {
         if (paisajeButtons[i] == 0 && (clickOn[0] == i  || clickOn[1] == i  || clickOn[2] == i  || clickOn[3] == i  || clickOn[4] == i )) {
           println("mira si hay un cero en el botón = " + i);
           if (i == clickOn[0]) {
             println("quita el botón 0");
             clickOn[0] = clickOn[1];
             clickOn[1] = clickOn[2];
             clickOn[2] = clickOn[3];
             clickOn[3] = clickOn[4];
             clickOn[4] = -1;
             counterButtons --;
           }
            if (i == clickOn[1]) {
             println("quita el botón 1");
             clickOn[1] = clickOn[2];
             clickOn[2] = clickOn[3];
             clickOn[3] = clickOn[4];
             clickOn[4] = -1;
             counterButtons --;
           }
            if (i == clickOn[2]) {
             println("quita el botón 2");
             clickOn[2] = clickOn[3];
             clickOn[3] = clickOn[4];
             clickOn[4] = -1;
             counterButtons --;
           }
            if (i == clickOn[3]) {
             println("quita el botón 3");
             clickOn[3] = clickOn[4];
             clickOn[4] = -1;
             counterButtons --;
           }
            if (i == clickOn[4]) {
             println("quita el botón 4");
             clickOn[4] = -1;
             counterButtons --;
           }
         }
       }
     }
