Ternary Operator Java SE 8 Programmer I question

class TernaryOperator
{
public static void main(String args[])
 {

(10>20)?10:20;

 }

}

is this code is valid ?

Output:

D:\Java8>javac TernaryOperator.java

(10>20)?10:20;
       ^
1 error

You Should assign value for TernaryOperator.

Modified code :

class TernaryOperator
{
public static void main(String args[])
 {

int a=(10>20)?10:20;

 }

}
