Exercise CheckOddEven (if-else): Write a program called CheckOddEven which prints "Odd Number" if the int variable “number” is odd, or “Even Number” otherwise. The program shall always print “BYE!” before exiting.

Hints: n is an even number if (n % 2) is 0; otherwise, it is an odd number.

/*
* Trying if-else statement and modulus (%) operator.
*/
public class CheckOddEven { // Save as "CheckOddEven.java"
public static void main(String[] args) { // Program entry point
int number = 49; // Set the value of "number" here!
System.out.println("The number is " + number);
if ( ...... ) {
System.out.println( ...... );
} else {
System.out.println( ...... );
}
System.out.println( ...... );
}
}
Exercise CheckPassFail (if-else): Write a program called CheckPassFail which prints "PASS" if the int variable "mark" is more than or equal to 50; or prints "FAIL" otherwise. The program shall always print “DONE” before exiting.

Hints:

/*
* Trying if-else statement.
*/
public class CheckPassFail { // Save as "CheckPassFail.java"
public static void main(String[] args) { // Program entry point
int mark = 49; // Set the value of "mark" here!
System.out.println("The mark is " + mark);

if ( ...... ) {
System.out.println( ...... );
} else {
System.out.println( ...... );
}
System.out.println( ...... );
}
}
Take note of the source-code indentation!!! Whenever you open a block with '{', indent all the statements inside the block by 3 or 4 spaces. When the block ends, un-indent the closing '}' to align with the opening statement.
