The "?:", or Ternary operator in PHP, Java, C and other languages is essentially shorthand for a block of code like

if ($a==1) {

print "A is 1!";

} else {

print "A is not 1!";

}

Using the ternary operator, it becomes

print ($a==1)?"A is 1!":"A is not 1!";

Cool, huh?

Or, in java

public class !CondOpTest? {

public static void main(String[] args) {

new !CondOpTest?(new Integer(args[0?));

}

public !CondOpTest?(Integer a) {

if (a.intValue()==1) {

System.out.println("A is 1!");

} else {

System.out.println("A is not 1!");

}

}

}

becomes

public class !CondOpTest? {

public static void main(String[] args) {

new !CondOpTest?(new Integer(args[0?));

}

public !CondOpTest?(Integer a) {

System.out.println((a.intValue()==1)?"A is 1!":"A is not 1!");

}

}

Note: It's great for making spaghetti code!
