Today, fyhao gives you another Java Certification Question, see if you can answer it right. More practice before you earn a certification.
Q4
Develop code that implements all forms of loops and iterators, including the use of for, the enhanced for (for-each), do, while, labels, break, and continue; and explain the values taken by loop counter variables during and after loop execution.
2) Given:
5. public class Buddy {
6. public static void main(String[] args) {
7. def:
8. for(short s = 1; s < 7; s++) {
9. if(s == 5) break def;
10. if(s == 2) continue;
11. System.out.print(s + “.”);
12. }
13. }
14. }
What is the result?
a) 1.
b) 1.2.
c) 1.3.4. (*)
d) 1.2.3.4.
e) 1.3.4.5.6.
f) 1.2.3.4.5.6.
g) Compilation fails.
Q5
What will happen when you attempt to compile and run the following code?
public class Agg{
static public long i=10;
public static void main(String argv[]){
switch(i){
default:
System.out.println(“no value given”);
case 1:
System.out.println(“one”);
case 10:
System.out.println(“ten”);
case 5:
System.out.println(“five”);
}
}
}
A. Compile time error
B. Output of “ten” followed by “five”
C. Output of “ten”
D. Compilation and run-time error because of location of default
Is it simple to you?
