It’s a very simple program asked in interviews.
What will be output when Try to print string with null in output in java ?
public class PrintStringWithNull {
public static void main(String[] args) {
System.out.println("a" + null);
System.out.println(null + "a");
}
}
|
This program might look confusing at first look and looks like will end end up in NullPointerException, but it won’t.
//output
anull
nulla
