the ? and : operators

[Gaia Nathan]

Can someone tell me what the ? and : operators do?
I can't find a reference to them.

[Sunetra Saha]

they make up a consolidated if-else syntax.
You can write the following if statement
if(condA)
{ statementA;
}else statementB;
as
condA?statementA:statementB

Hi!
Actually, the ? : is called the Conditional Operator. Some code to illustrate what Sunetra wrote:

public class Q {
public static void main(String[] args) {
int i = (int) (Math.random()*2 + 1);
int j;
if (i == 1) 
j = 1;
else
j = 2;
int k = (i == 1) ? 1 : 2;
System.out.println(i + "\n" + j + "\n" + k);
}
}

Hope this helps!

Thanks Sunetra, Kaspar. Both your replies made it very clear for me.
