Anushree,
That is becoz of the position of default statement.There is no break statement after default, so the next case is considered & "a" is printed. Only when it finds break statement, the switch statement is left.
Change your program to the following and nothing will be printed.

class switch1{
public static void main(String args[])
{
char ch='c';
switch(ch)
{
default: break;
case 'a':System.out.println("a");break;
case 'b':System.out.println("b");break;
}
}
}  

Remember : Execution of the BREAK statement only transfers control out of the switch statement, else execution of the next label continues.
