Unclosed Character Literal error

Question

Got the error "Unclosed Character Literal" , using BlueJ, when writing:

class abc
{
   public static void main(String args[])
   {
       String y;
       y = 'hello';
       System.out.println(y);
   }
}

But I can't figure out what is wrong. Any idea?

Thanks.

Answer 1

In Java, single quotes can only take one character, with escape if necessary. You need to use full quotation marks as follows for strings:

y = "hello"; 

You also used

System.out.println(g); 

which I assume should be

System.out.println(y); 

Note: When making char values (you'll likely use them later) you need single quotes. For example:

char foo='m'; 

Answer 2

Java uses double quotes for "String" and single quotes for 'C'haracters.
