7. THE JAVA CHALLENGE!

8. Question 1:
What will happen when you attempt to compile and run the following code?
public class MyClass
{
static
{
int one = 5;
}
static int one,two;
public static void main(String args[])
{
one--;
operate();
System.out.println(one + two + ++one);
}
public static void operate()
{
two = one++ + ++one;
}
}
A. Compile-time error
B. Run-time error
C. prints : 2
D. prints : 3
E. prints : 5
F. prints : 7

9. Question 2:
What is the result when you compile and run the following code?
public class MyClass
{
static void operate()
{
System.out.println("Inside operate().");
throw new IllegalAccessException("BAD!");
}
public static void main(String args[])
{
try
{
operate();
}
catch (IllegalAccessException e)
{
System.out.println("Caught " + e);
}
}
}
A. Compilation error
B. Runtime error
C. Compile successfully, nothing is printed.
D. Inside operate(). followed by caught: java.lang.IllegalAccessExcption: BAD!

10. Question 3:
What will happen when you attempt to compile and run the following code (there are two correct answers)?
public class MyClass extends Thread
{
String myVar;
MyThread(String name)
{
myVar = name;
}
public void run()
{
for(int i=0; i<50;i++)
{
System.out.println(myVar);
}
}
public static void main(String args[])
{
try
{
MyThread t1 = new MyThread("t1");
MyThread t2 = new MyThread("t2");
t1.start();
// Position1
t2.start();
}
catch(InterruptedException ex)
{
}
}
}
A. The above code in its current condition will not compile.
B. In order to make the MyThread class prints "t1" (50 times) followed by "t2" (50 times), t1.join(); can be placed at //Position1 position.
C. In order to make the MyThread class prints "t1" (50 times) followed by "t2" (50 times), t1.sleep(50); can be placed at //Position1 position.
D. In order to make the MyThread class prints "t1" (50 times) followed by "t2" (50 times), t1.run(); can be placed at //Position1 position.
E. In order to make the MyThread class prints "t1" (50 times) followed by "t2" (50 times), there is no need to write any code.
