The following code is written: double d_value = 32.0; d_value = 40: int j = 2; d_value = j; Which of the following would best describe this scenario? Choose the best answer from the following options. This code is an example of conversion and so this code will run. This code fails because for one of the lines, the left side of the equals symbol and the right side are different data types This code will not run because Java cannot support conversion and casting needs to be specified Given the following: public class Tree { int number_leaves; int number_roots; /* etc. */ } public class AppleTree extends Tree { void printApple() {...}; }. // printApple output "Apple" public class OrangeTree extends Tree { void printOrange() {...}; } // printOrange outputs "Orange" public class Lemon Tree extends Tree { void printLemon() {...}}} // printLemon outputs "Lemon" Tree tr 1 = new LemonTree(); Tree tr2 = new Orange Tree(); tr1 = tr2; Tree tr = tr1; tr.printLemon(); Please choose the right answer: Lemon is printed on the screen Orange gets printed on the screen Nothing gets printed on the screen because there is an error or issue in the code Apple is printed on the screen Given: public interface Product {... } // has seven public methods public interface Cost {... } // has three public methods public class NetworkAdapter extends Product {...} // inherits all of the methods public class NetworkSwitch implements Product implements Cost {...} Select the best choice that relates to the code above: NetworkSwitch should change from implementing Cost to extending Cost Network Switch should change to extending Product instead of implementing it NetworkAdapter should change to implementing only NetworkAdapter should be implementing, and NetworkSwitch should be extending Product
