I have a string that should contain one name
then &
and then second name
.
and two consecutive &
should not occur. Also last character should not be &
.
i have tried following code but this is not working
System.out.println("45345&&345".matches("(^(?!&)(?!.*&&)[0-9&]+(?<!&))$"));
regex is as (^(?!&)(?!.*&&)[0-9&]+(?<!&))$
but its not working!! Can you please help me.
Just one &
on line and doesn't start or end with &
:
^[^&]+&[^&]+$
Can contain multiple &
, but not consecutive ones and doesn't start or end with &
:
^(?:[^&]+&)+[^&]+$
