JAVA on Flow Controls (if-else/switch case)

( I ) 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 : [Recommended IDE - Eclipse Ganymede 32 bit]

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 {
System.out.println( ...... );
}
}
}

( II )Exercise CheckOddEven (if-else): 

 
Write a program called CheckOddEven which prints "Odd Number" if the int variable “number” is odd, or “Even Number” otherwise.
Hints: n is an even number if (n % 2) is 0.

public class CheckOddEven { // saved as "CheckOddEven.java"
public static void main(String[] args) {
int number = 49; // set the value of number here!
System.out.println("The number is " + number);
if ( ...... ) {
System.out.println( ...... );
} else {
System.out.println( ...... );
}
}
}

( III )PrintNumberInWord (nested-if, switch-case):
 

Write a program called PrintNumberInWord which prints "ONE", "TWO",... , "NINE", "OTHER" if the int variable "number" is 1, 2,... , 9, or other, respectively. 

Use (a) a "nested-if" statement; (b) a "switch-case" statement.

Hints:

public class PrintNumberInWord
{ //saved as"PrintNumberInWord.java"
public static void main(String[] args)
{
int number = 5;
// Using nested-if
if (number == 1) {
System.out.println("ONE");
} else if (......) {
......
} else if (......) {
......
......
} else {
......
}
// Using switch-case
switch(number) {
case 1: System.out.println("ONE"); break;
case 2: ......
......
......
default: System.out.println("OTHER");
}
}
}
