switch ( value )
{
case 1: case 2: case3:
  do-something;
  break;
  
case 4: case 5: case6: case 7:
  do-something;
  break;

case 8: case 9: case 10:
  do-something;
  break;
}

switch with Strings

Recall the syntax of the switch statement:

switch ( expression )
{
  case label1:
    statementList1 
    break;

  case label2:
    statementList2 
    break;

  case label3:
    statementList3 
    break;

  . . . other cases like the above

  default:
     defaultStatementList 
}

Starting with Java 7.0 the expression can be a String reference and the case labels can be String literals.

Matching of the expression with the case labels is done as if by String.equals().
