Q64. Given:
public class ColorTest {
public static void main(String[] args) {
String[] colors = {"red", "blue","green","yellow","maroon","cyan"};
int count = 0;
for (String c : colors) {
if (count >= 4) {
break;
}
else {
continue;
}
if (c.length() >= 4) {
colors[count] = c.substring(0,3);
}
count++;
}
System.out.println(colors[count]);
}
}
What is the result?
A. Yellow
B. Maroon
C. Compilation fails
D. A StringIndexOutOfBoundsException is thrown at runtime.
Answer: C
Explanation: The line, if (c.length() >= 4) {, is never reached. This causes a compilation error.
Note: The continue statement skips the current iteration of a for, while , or do-while loop. An unlabeled.break.statement terminates the innermost.switch,.for,.while, or.do-while.statement, but a labeled.break.terminates an outer statement.
Q65. Given:
class Overloading {
int x(double d) {
System.out.println("one");
return 0;
}
String x(double d) {
System.out.println("two");
return null;
}
double x(double d) {
System.out.println("three");
return 0.0;
}
public static void main(String[] args) {
new Overloading().x(4.0);
}
}
What is the result?
A. One
B. Two
C. Three
D. Compilation fails.
Answer: D

Q68. Given:
package p1;
public interface DoInterface {
void method1(int n1); // line n1
}
package p3;
import p1.DoInterface;
public class DoClass implements DoInterface {
public DoClass(int p1) { }
public void method1(int p1) { } // line n2
private void method2(int p1) { } // line n3
}
public class Test {
public static void main(String[] args) {
DoInterface doi= new DoClass(100); // line n4
doi.method1(100);
doi.method2(100);
}
}
Which change will enable the code to compile?
A. Adding the public modifier to the declaration of method1 at line n1
B. Removing the public modifier from the definition of method1 at line n2
C. Changing the private modifier on the declaration of method 2 public at line n3
D. Changing the line n4 DoClass doi = new DoClass ( );
Answer: C
