In Java you can't return multiple values per method. Methods much return exactly one value (or be declared void and return exactly 0 values, or throw an exception).
There are many solutions that could solve your problem.
An easy one is to concatenate the two strings together:
return name + " " + venue;
This likely isn't going to be very effective, though. The second solution is to create two methods that return each item separately.
public String getName()
{
return name;
}
public String getVenue()
{
return venue;
}
This is the implementation route I would take. It's concise, and you can get either value by itself.
Another method you could take is to use an array/some other object to contain both strings and return that object:
public String[] getDetails()
{
return new String[] {name,venue};
}
