Please try to explain the answers as well. It will be highly appreciated.

• Output of the following expression:

5 * 4 % 2 = ?

• Output of a loop:
  • Example: What will be the output of the Java code (Assume all variables are properly declared.)

num = 10;

while (num <= 32)

num = num + 5;

System.out.println(num);

• What will be the output of the Java code (Assume all variables are properly declared.)

public class test

{

public static void main(String[] args)

{

int n1 = 8;

int n2 = 3;

double answer = (double ) n1 / n2;

System.out.println(The answer is + answer);

}

}

Note: Check with and without type casting.

• What will be the output of the Java code (Assume all variables are properly declared.)

for (int i = 1; i <= 3; i++)

{

for (int j = 2; j <= 3; j++)

{

System.out.println(I + ,+ j);

}

}

Answer:

• Question:

Suppose x = 19.5. What will be the output of the statement

System.out.println((int)(x) % 3);

• What will the output of the following Java code (Assume all variables are properly declared and the input is 3 4 1).

}

Answer:

}

Answer:

• What is the output of the following Java code:

int alpha = 5;

int beta = 4;

switch (beta)

{

case 2:

alpha = alpha + 2;

case 4:

alpha = alpha + 4;

break;

case 6:

alpha = alpha + 6;

default:

alpha = alpha + 10;

}

System.out.print(alpha);

a. 7 c. 11

b. 9 d. 15

• What is the output of the following code?

int i;

int result = 5;

for (i = 0; i <= 2; i++)

{

result = result + 2;

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

}

Write a line of code to call a method named printMe. The method has no return value and no arguments.
