java - 将布尔值更改为是 否

2022-01-19 00:00:00 boolean java swing

我有一个布尔数组，稍后需要将它们显示给用户，而不是显示真或假，我想显示是或否.有人可以帮我解决这个问题吗?

I have a boolean array and need them displayed to the user later, as opposed to showing true or false I'd like to display yes or no. Could someone please help me on this?

    public static boolean[] seen (boolean[] birds)
    {   String quit = "100";
        String ans = "";
        while(!ans.equals(quit))
        {   ans=JOptionPane.showInputDialog(null,"Which bird are you reporting? 
   1) Blue Tit
   2) Blackbird
   3) Robin
   4) Wren
   5) Greenfinch");
            if (ans.equals("1"))
            {   birds[0]=true;
            }
            else if (ans.equals("2"))
            {   birds[1]=true;
            }
            else if (ans.equals("3"))
            {   birds[2]=true;
            }
            else if (ans.equals("4"))
            {   birds[3]=true;
            }
            else if (ans.equals("5"))
            {   birds[4]=true;
            }
        }
        return birds;   
    }
public static void display(boolean[] newbirds)
    {   JOptionPane.showMessageDialog(null,"newbirds[0]+" "+newbirds[1]+" "+newbirds[2]+" "+newbirds[3]+" "+ newbirds[4]+"");
    }
}

我希望数组 newbirds[i] 显示为 yes 或 no 格式，有人可以帮忙吗?

I would like the arrays newbirds[i] displayed as yes or no format, could someone help?

推荐答案

这可用于循环数组并打印yes"或no":

This can be used to loop over the array and print "yes " or "no " :

            boolean[] newbirds = {false, true, true};
            StringBuilder sb = new StringBuilder();
            for(boolean bird : newbirds){
                sb.append(bird? "yes " : "no "); 
            }
            System.out.println(sb.toString());
