What will be the output of the above code?
(a)
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 (a) output.

{
public static void main(String args[]) throws IOException {
char c;
BufferedReader obj = new BufferedReader(new InputStreamReader(System.in));
do
{
c = (char) obj.read();
System.out.print(c);
} while(c != 'q');
}
}
What will be the output of the following Java program if input given is ‘abcqfghqbcd’?
(a)
(a) 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
