Many cases with one break

[karuga]

public class SwitchClass
{
public static void main(String[] kiarie)
{
int points =12;
switch(points)
{case 12:
System.out.println("A");
System.out.println("Excellent!");

case 11:
System.out.println("A-");
System.out.println("Very Good!");

case 10:
System.out.println("B+");
System.out.println("Good");

case 9:
System.out.println("B");
System.out.println("Good");

case 8:
System.out.println("B-");
System.out.println("Good");
break;
case 7:
System.out.println("C+");
System.out.println("Fair");
break;

case 6:
System.out.println("C");
System.out.println("Fair");
break;

case 5:
System.out.println("C-");
System.out.println("Fair");
break;

case 4:
System.out.println("D+");
System.out.println("poor");
break;
case 3:
System.out.println("D");
System.out.println("poor"); //its optional for default to have break
break;

case 2:
System.out.println("D-");
System.out.println("poor");
break;

case 1:
System.out.println("E");
System.out.println("very poor");
break;

default:
System.out.println("Bad entry");
System.out.println("please check the points and enter again");
break;
}
}
}



I wanted Cases 12,11,10,9 and 8 to have just the statements for case 8,hence only one break.However,if i switch 12,all statements up to first break are shown in output.What is causing this?

if each case block has more than one statement, you must enclose all statements for that case block in curly braces. when compiled, all of the case blocks are assumed to be part of the case block for "12".
