1.1 Exercises on Conditional (Decision)
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.
Hints:
------------------------------------------------- public class CheckPassFail { // saved as "CheckPassFail.java"
-------------------------------------------------
public static void main(String[] args) {
-------------------------------------------------
int mark = 49; // set the value of mark here!
-------------------------------------------------
System.out.println("The mark is " + mark);
-------------------------------------------------
------------------------------------------------- if ( ...... ) {
-------------------------------------------------
System.out.println( ...... );
-------------------------------------------------
} else {
-------------------------------------------------
