First<\/strong> thing I noticed Book constructors are the main issue. <\/p>\n

Your first constructor has two parameters title<\/code> and year<\/code>.<\/p>\n

Book b1 = new Book(title, year);<\/code><\/p>\n

But in the second constructor has one parameter title<\/code> and you have missed the year<\/code>. That’s why you didn’t get year<\/code>.<\/p>\n

Book b2 = new Book(title);<\/code> <\/p>\n

You can correct it by editing the above statement from the below statement.<\/p>\n

Book b2 = new Book(title, year);<\/code> <\/p>\n

Second<\/strong> thing you try to print object like System.out.println(b2);<\/code> without implementing toString()<\/code> method.<\/p>\n

Please try following code. You can get the expected output without directly using the Book()<\/code> constructor.<\/p>\n

class Test {\n\n   public static void main(String[] args) {\n\n      Book b1 = new Book();\n      b1.setYear(1975);\n      b1.setTitle(\"The God and the Sword\");\n      System.out.println(b1);\n      b1.setRead(true);\n      System.out.println(b1);\n\n      Book b2 = new Book();\n      b2.setTitle(\"The Light of Spirind\");\n      b2.setYear(1960);\n      System.out.println(b2);\n      b2.setRead(true);\n      System.out.println(\"The book has now been read: \" + b2.isRead());\n   }\n}\n\nclass Book {\n\n   private boolean read;\n   private int year;\n   private String title;\n\n   public boolean isRead() {\n      return read;\n   }\n\n   public void setRead(boolean read) {\n      this.read = read;\n   }\n\n   public int getYear() {\n      return year;\n   }\n\n   public void setYear(int year) {\n      this.year = year;\n   }\n\n   public String getTitle() {\n      return title;\n   }\n\n   public void setTitle(String title) {\n      this.title = title;\n   }\n\n   Book() {\n\n   }\n\n   public String toString() {\n      return \"This Book\\ntitle: \" + getTitle() + \",\\n \" + \"year of publication: \" + getYear() + \",\\n \" + \"read: \" + isRead();\n   }\n}\n<\/code><\/pre>\n<\/p><\/div>\n
