Help with Switch-Case Statement

Question

How do you get this in a switch-case statement or work with it?
          if (age < 70) {
                    JOptionPane.showMessageDialog(null, "People that are below the 70s are nothing special.");
          else if (age > 69 && age < 80) {
                    JOptionPane.showMessageDialog(null,  "People that are in their 70s are called septuagenarian.");
          else if (age > 79 && age < 90) {
                    JOptionPane.showMessageDialog(null,  "People that are in their 80s are called octogenarian.");
          else if (age > 89 && age < 100) {
                    JOptionPane.showMessageDialog(null,  "People that are in their 90s are called nonagenarian.");
          else (age > 99 && age < 110) {
                    JOptionPane.showMessageDialog(null,  "People that are in their 100s are called centenarian.");
               }Thanks~

As per Java Specification, swtich case expects an integer and boolean cannot be used as param for switch.
In your case switch can be used like this.
int index = age /10;
switch(index) {
case 1:
case 2:
case 3:
case 4:
case 5:
case 6:
Your First case
break;
case 7:
your second case
break;
case 8:
third case
break;
case 9:
fourth case
break;
default:
fifth case
break;
Take note of the break statements. Its very important. But I wont prefer in this case. Code looks awkward and is not so meaningful.....
