Demo Questions
Question 1
Given:
public class App {
// Insert code here
System.out.print("Welcome to the world of Java");
}
}
Which two code fragments, when inserted independently at line // Insert code here, enable the program to execute and print the welcome message on the screen?
- static public void main (String [] args) {
- static void main (String [] args) {
- public static void Main (String [] args) {
- public static void main (String [] args) {
- public void main (String [] args) {
Correct answer: AD
Explanation:
Incorrect:Not B: No main class found.Not C: Main method not found notE: Main method is not static. Incorrect:
Not B: No main class found.
Not C: Main method not found not
E: Main method is not static.
Question 2
Given the code fragment:
public class Test {
public static void main(String[] args) {
boolean isChecked = false;
int arry[] = {1,3,5,7,8,9};
int index = arry.length;
while ( <code1> ) {
if (arry[index-1] % 2 ==0) {
isChecked = true;
}
<code2>
}
System.out.print(arry(index]+", "+isChecked));
}
}
Which set of changes enable the code to print 1, true?
- Replacing <code1> with index > 0 and replacing <code2> with index-;
- Replacing <code1> with index > 0 and replacing <code2> with -index;
- Replacing <code1> with index > 5 and replacing <code2> with -index ;
- Replacing <code1> with index and replacing <code2> with -index ;
Correct answer: A
Explanation:
Note: Code in B (code2 is -index;). also works fine. Note: Code in B (code2 is -index;). also works fine.
Question 3
Given:
public class TestLoop {
public static void main(String[] args) {
int array[] = {0, 1, 2, 3, 4};
int key = 3;
for (int pos = 0; pos < array.length; ++pos) {
if (array[pos] == key) {
break;
}
}
System.out.print("Found " + key + "at " + pos);
}
}
What is the result?
- Found 3 at 2
- Found 3 at 3
- Compilation fails
- An exception is thrown at runtime
Correct answer: C
Explanation:
The following line does not compile:System.out.print("Found " + key + "at " + pos);The variable pos is undefined at this line, as its scope is only valid in the for loop.Any variables created inside of a loop are LOCAL TO THE LOOP. The following line does not compile:
System.out.print("Found " + key + "at " + pos);
The variable pos is undefined at this line, as its scope is only valid in the for loop.
Any variables created inside of a loop are LOCAL TO THE LOOP.
