问题描述

如何打印出方法的结果？我想打印出翻译的返回但它显示为true或false。建议请。

How do I print out the result of a method? I want to print out the return of translate but it displays true or false. Suggestions please.

/**
     * @returns the string "yes" if "true" and "no" if false
     */
    public String translate(boolean trueOrFalse)    
       {       
        if(pback == true)
            {
                return "yes";
            }
        else
            {
                return "no";
            }
        }
    /**
     * Display book info
     */
    public void displaybook()
        {
            System.out.println("Title: " + title);
            System.out.println("Author: " + author);
            System.out.println("ISBN: " + isbn);
            System.out.println("Pages: " + pages);
            System.out.println("Paperback: " + pback);
            System.out.println("Suggested Price: " + price);            
        }

推荐答案

看起来你错误地连接起来了您的变量 pback 而不是以下语句中的translate方法的结果：

It looks like you mistakenly concatenated your variable pback instead of the result of your translate method in the following statement:

System.out.println("Paperback: " + pback); 

相反，将该语句替换为

System.out.println("Paperback: " + translate(pback));
