java-将boolean更改为yes [英] java -change boolean to yes no

问题描述

我有一个布尔数组，需要稍后将它们显示给用户，而不是显示true或false，我想显示yes或no.有人可以帮我吗?

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? \n   1) Blue Tit\n   2) Blackbird\n   3) Robin\n   4) Wren\n   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]+"");
    }
}

我希望将newbirds [i]数组显示为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

这可用于遍历数组并显示"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());
