Question 4

Analyze the following code. public class Test { int x; public Test(String t) { System.out.println("Test"); } public static void main(String[] args) { Test test = null; System.out.println(test.x); } }

technology programming languages

The program has a syntax error because test is not initialized.
The program has a syntax error because x has not been initialized.
The program has a syntax error because you cannot create an object from the class that defines the object.

technology programming languages

The program has syntax errors because the variable radius is not initialized.
The program has a syntax error because a constant PI is defined inside a method.
The program has no syntax errors but will get a runtime error because radius is not initialized.
The program compiles and runs fine

Answer

Correct Option: A

Question 7

Analyze the following code. public class Test { int x; public Test(String t) { System.out.println("Test"); } public static void main(String[] args) { Test test = new Test(); System.out.println(test.x); } }

technology programming languages

The program has a syntax error because System.out.println method cannot be invoked from the constructor.
The program has a syntax error because x has not been initialized.
The program has a syntax error because you cannot create an object from the class that defines the object.
The program has a syntax error because Test does not have a default constructor.
