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 type
