When the following code is executed an error is encountered and the program crashes. On which line do you think the error is encountered?

You may assume that all required classes have been defined elsewhere.

Which of the following loops will execute the statements at least once, even though the condition is false initially?

What will be printed when the following code is executed?

    String firstname = "John";
    String surname = "Smith";
    surname.toUpperCase(); 
    System.out.print(firstname.charAt(0) + " " + surname);

What does the following Java code display on the screen?

int rows = 4; 
String output = "";
for (int i = 0; i < rows; i++)
{
     output = output + i;
     for (int j = 0; j < i; j++) 
          output = output + "*";
}
System.out.print(output);

public void displayNames()
{
    int i = 5;
    String[] names = new String[10];
    System.out.println(names[i]);
}

What will be the output when displayNames executes?

You have been provided with the following loop. It is required to do some processing on all the odd numbers between one and maxNumber inclusive.

int index = 1;
do
{
    //Some processing code is done here
    //insert line here
} while (index < maxNumber);

What line of code can be inserted before the end of the loop, so that the loop only checks the odd numbers between 1 and maxNumber? Multiple responses are allowed — select all that apply.

When the following code is executed an error is encountered and the program crashes. On which line do you think the error is encountered?

You may assume that all required classes have been defined elsewhere.

How many rows will be displayed on the screen when the following code is executed?

for (int index = 0; index <= 20; index++)
{
   System.out.println("The current number is : " + index);
   index++;
}

You have been provided with the following class diagram:

Package objPack = new Package();

Based on the provided information only, how many objects are created in total (external and internal) when the code is executed?

What is the value of x after the execution of the following program segment?

int x = 1;
while (x < 2) 
{
    x = 10;
    x = x - 5;
}
