Java - decision making and looping

What will be the output of the following Java code?

int a = 10, b = 20;

if (a < b) { if (b > 15)

{

System.out.println("TRUE");

} else

{

System.out.println("FALSE");

}

}

else

{

System.out.println("NONE");

}

• TRUE
  
  
  

• FALSE

• NONE

• Compilation error

How does a while loop start?

• The loop executes the block of code if the condition is false.

• The loop executes the block of code at least once before checking the condition.

• The loop executes the block of code if the condition is true.

• The loop condition is checked after executing the block of code.

What does the following code print?

int i = 0;

while (i < 3)

{

System.out.println("Hi");

i++;

}

• Hi
  

• Hi printed 3 times
  

• Hi printed 4 times
  

• The code results in an infinite loop

What is the use of the break statement in loops?

• It terminates the loop and transfers execution to the statement immediately following the loop

• It skips the current iteration of the loop and continues with the next iteration.

• It causes the loop to skip the remainder of its body and immediately retest its condition prior to reiterating.

• It is used to return a value from a method with a non-void return type.

What will the following switch statement output for int day = 4; ?

switch (day)

{

case 1:

System.out.println("Monday");

break;

case 2: System.out.println("Tuesday");

break;

case 3: System.out.println("Wednesday");

break;

case 4: System.out.println("Thursday");

break;

case 5: System.out.println("Friday");

break;

default: System.out.println("Weekend");

}

• Monday

• Tuesday

• Thursday

• Weekend

What is the output of the following code ?

int i = 10;

do

{

System.out.println(i);

i--;

} while (i > 10);

• Prints 10

• Prints numbers from 10 to 1

• No output

• Compilation error

Which of the following for loop declarations is valid in Java?

• for (int i = 0, i < 5; i++)

  {

  }

• for (int i = 0; i < 5; i++)

  {

  }

• for i = 1 to 10

  {

  }

• for (int i; i < 5; i++)

  {

  }

Given the following Java code snippet, what is the output?

for (int i = 0; i <= 5; i++)

{

if (i == 3)

{

continue;

}

System.out.print(i + " ");

}

• 0 1 2 3 4 5
  

• 0 1 2 4 5
  

• 1 2 4 5
  

• 0 1 2

Which of the following is the correct syntax for an if-else statement in Java?

• if (condition) statement1;

  else

  statement2;

• if condition: statement1;

  else:

  statement2;

• if

  {

  condition

  }

  statement1;

  else

  statement2;

• if (condition) then statement1;

  else

  statement2;

Which Java feature allows executing one block of code out of multiple blocks based on the condition at runtime?

• Loops
  

• Decision Making
  

• Exception Handling
  

• Multithreading
