doubt in String

[manas ranjan mandal]

I want to know that what is the different between new StringBuffer('A') and new StringBuffer("A")?

Thanks in advance

What is the output of this test and why:

public class SBTest {
 
   public static void main(String[] args) {
      StringBuffer sbWithString = new StringBuffer("A");//line 1
      StringBuffer sbWithChar = new StringBuffer('A');//line 2
 
      System.out.println(sbWithString.toString());
      System.out.println(sbWithChar.toString());
   }
 
}

Is there a StringBuffer constructor that takes a char as a parameter? If not, then which constructor is being invoked at line 2?
