FILL IN THE BLANK QUESTION

Fill in the blanks such that the following code must display "Hello" on the screen.
int x = 19;
if(x ___ 19) System.out.print("Hello"); else System.out.print("Bye");
Answer explanation
To display 'Hello', the condition must be true. Using '==' checks if x is equal to 19. Therefore, the correct choice is '==' which allows the code to print 'Hello' when x is 19.

MULTIPLE CHOICE QUESTION

Choose the most appropriate of the options that apply to the following code segment:
char section = 'C';
switch(section) {
default: System.out.println("Mix batch");
case 'A': System.out.println("Toppers"); break;
}
Compiler Error: the default case not allowed to be written before other cases.
Compiler error : Must use break after every case
Compiler error: Cannot use char variables as switch parameter
Output:
Mix batch
Toppers
Output:
Mix batch
Answer explanation
The switch statement evaluates 'section' as 'C', which does not match any case. It falls to the default case, printing 'Mix batch'. Due to missing break statement after the default case, the case 'A' will also be executed, so 'Toppers' is also printed. Thus, the output is:
Mix batch
Toppers

Spot the location(s) reported for syntax error in the following code:
class Demo{
public static void main(String args[]) { //Line-1
int expense = 1_000; //Line-2
while(expense++ < 1100) ; //Line-3
{ boolean canSpendMore = true; return; } //Line-4
System.out.println(expense); //Line-5
} }
Tick all that apply.
Line-1
Line-2
Line-3
Line-4
Line-5
Answer explanation
Line-5 has a syntax error because it is outside of any method or block after the return statement in Line-4. The return statement exits the method, making any code after it unreachable.
