d. protected

Each class in java has at least one constructor even if you don't create one.
Select one:
a. false
b. true

Analyze the following code.
public class Test {
private int t;
public static void main(String[] args) {
int x;
System.out.println(t);
}
}
Select one:
a. t is non-static and it cannot be referenced in a static context in the main method.
b. The program compiles and runs fine.
c. The variable t is not initialized and therefore causes errors.
d. The variable x is not initialized and therefore causes errors.

An attribute that is shared by all objects of the class is coded using ________.
Select one:

b. an instance variable
c. a static method
d. an instance method

c. private
d. Use the default modifier

.
;int count = 0
}(while (count < 100
Point A//
++System.out.println("Welcome to Java!"); count
Point B//
;{
Point C//
Select one:
a. count < 100 is always true at Point C
b. count < 100 is always false at Point A
c. count < 100 is always false at Point C
d. count < 100 is always true at Point B
