What will be the output of the above code?

public class Demo{

public static void main(String[] arr){

Integer num1 = 100;

Integer num2 = 100;

Integer num3 = 500;

Integer num4 = 500;

if(num1==num2){

System.out.print("num1 == num2");

}

else{

System.out.print("num1 != num2");

}

if(num3 == num4){

System.out.print("num3 == num4");

}

else{

System.out.print("num3 != num4");

}

}

}

Above code will give ______ output.

class Input_Output

{

public static void main(String args[]) throws IOException {

char c;

BufferedReader obj = new BufferedReader(new InputStreamReader(System.in));

} while(c != 'q');

}

}

What will be the output of the following Java program if input given is ‘abcqfghqbcd’?

__________ is used to perform all input and output operations in Java.

Select the correct classes that fall under the checked exception category:

• ArithmeticException

• FileNotFoundException

• IllegalArgumentException

• IOException

For any program to design, the following are important steps:

• Algorithm

• VDT table

• Data flow diagram

• Coding

In a good algorithm, we see the following features:

• Precise

• Clear IO operation

• Finite

• Grammatically correct
