java - Implementation of switch case for check box -

is there way implement switch case checkbox?

example: have 4 checkboxes, if selected 2 checkboxes, how trigger case output want?

 double exam = 0.0, assign = 0.0, quiz = 0.0, ct = 0.0;                  if (examchkbox.isselected()) {                 exam = double.parsedouble(examtextfield.gettext());                 }                 if(ctchkbox.isselected()) {                 ct = double.parsedouble(cttextfield.gettext());                     }                 if(quizchkbox.isselected()) {                 quiz = double.parsedouble(quiztextfield.gettext());                     }                 if(asschkbox.isselected()) {                 assign = double.parsedouble(asstextfield.gettext());                     }                 if (!(exam + ct + quiz + assign == 100)) {                 markerrorlbl.settext("total marks must 100");                 }                 else {                    // implementation of code here                 } 

design view.

let ticked exam , class test, want select value in text field , store marks using switch case. possible?

this thing want i've no idea how implement checkbox.

switch(x)          {             case 1 : = new exam(marks)   ;total+=marks;  break;             case 2 : = new test(marks)   ;total+=marks; break;             case 3 : = new quiz(marks)   ;total+=marks; break;             case 4 : = new assignment(marks) ;total+=marks;break;              } 

why want use switch instead of if statements have in code?

since can select 4 checkboxes independently each other, switch not best solution here. have 4 checkboxes, there 2^4 = 16 possible "check patterns":

int pattern = (cb1.isselected() ? 0b0001 : 0)             | (cb2.isselected() ? 0b0010 : 0)             | (cb3.isselected() ? 0b0100 : 0)              | (cb4.isselected() ? 0b1000 : 0);  switch (pattern) {     case 0b0001:         // code when checkbox 1 checked          break;     ...     case 0b0011:         // code when checkbox 1 , checkbox 2 checked         break;     ...     case 0b1011:         // code when checkbox 1, 2 , 4 checked         break;     ... } 

if use switch, need 16 cases. in contrast, need 4 if statements:

if (checkbox 1 checked) {     // code when checkbox 1 checked } if (checkbox 2 checked) {     // code when checkbox 2 checked  } ...     

note these 4 independent if statements, no else ifs there.
