Question
Analyze the following code. public class Test {intx; public Test(String t) {System out println(Test");} public static void main(String[] args) {Test test ¦ null; System out println(test.x);}} The program has a compile error because test is not initialized. The program has a compile error because x has not been initialized. The program has a compile error because you cannot create an object from the class that defines the object. The program has a compile error because Test does not have a default constructor. The program has a runtime NullPointerException because test is null while executing test.x. Analyze the following code. public dass Test {public static void main (String Q args) {double radius, final double PI-3.15169; double area middot radius * radius * PI; System .out. printin ("Area is " + area), }} The program has compile errors because the variable radius is not initialized. The program has a compile error because a constant PI is defined inside a method. The program has no compile errors but will get a runtime error because radius is not initialized. The program compiles and runs fine. is invoked to create an object. A constructor the main method A method with a return type A method with the void return typeExplanation / Answer
17) a) constructor
Constructor in java is a special type of method that is used to initialize the object.
Java constructor is invoked at the time of object creation. It constructs the values i.e. provides data for the object that is why it is known as constructor.
Rules for creating java constructor
There are basically two rules defined for the constructor.
