question

package game;  public class question { protected string qstn=""; protected string[] choices = new string[3]; protected boolean win; question(string qstn,string[] choices,boolean win){     this.qstn=qstn;     this.choices=choices;     this.win=win; } protected string getchoice(int i){     return choices[i]; } }

is working me....

  @override public void start(stage primarystage){     primarystage.settitle("millionare");     question[] questions=new question[14];     string[] questionnames={             "13425",             "13425",             "13425",             "13425",             "13425",             "13425",             "13425",             "13425",             "13425",             "13425",             "13425",             "13425",             "13425",             "13425",             "13425",     };     string[][] choices = {             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},             {"531","22354","33254","53424"},     };     boolean[] rights = {             false,             false,             false,             false,             false,             false,             false,             false,             false,             false,             false,             false,             false,             false,             false,     };     for(int i=0;i<questions.length;i++){         for(int j=0;j<questionnames.length;j++){             for(int y=0;y<choices.length;y++){                 for(int x=0;x<rights.length;x++){                     questions[i]=new question(questionnames[j],choices[y],rights[x]);                 }             }          }     }     text question=new text("answer questions win $1,000,000!");     button enter=new button("                                               start                                                           ");     button choice1=new button("choice 1");     button choice2=new button("choice 2");     button choice3=new button("choice 3");     button choice4=new button("choice 4");     observablelist<string> stages = fxcollections.observablearraylist(             "0",             "100",             "200",             "500",             "1000",             "2000",             "4000",             "8000",             "61000",             "50000",             "10000",             "250000",             "500000",             "1000000"             );     listview<string> lv=new listview<>(stages);     hbox hb1=new hbox();     hbox hb2=new hbox();      gridpane gp=new gridpane();     borderpane bp=new borderpane();     hb1.getchildren().add(question);     hb2.getchildren().add(enter);     gp.add(choice1, 1, 3);     gp.add(choice2, 2, 3);     gp.add(choice3, 3, 3);     gp.add(choice4, 4, 3);     enter.setonaction(new eventhandler<actionevent>(){         @override         public void handle(actionevent event) {             enter.setvisible(false);             question.settext(questions[0].qstn);              choice1.settext(questions[0].getchoice(0));             choice2.settext(questions[0].getchoice(1));             choice3.settext(questions[0].getchoice(2));             choice4.settext(questions[0].getchoice(3));         }     });     bp.settop(hb1);     bp.setcenter(gp);     bp.setright(lv);     bp.setbottom(hb2);     scene scene=new scene(bp,724,200);     primarystage.setscene(scene);     primarystage.show(); }
