Try catch inside switch java

  value2 = Double.parseDouble(txtDisplay.getText());
           
            switch(operand){
                case  '+':
                     answer = model.add(value1, value2);
                    break;
                    
                case '-':
                     answer = model.subtract(value1, value2);    
                     break;
                        
                case '*':
                     answer = model.multiply(value1, value2);
                    break;
                    
                case '/':
                     answer = model.divide(value1, value2);
                    break;
                    
                case 'p':
                      answer = model.power(value1, value2);
                      break;
                      
                
                    
            }

hello, here is my simple switch statement, this is the code after hitting the equals button of my scientific calculator.
But i need to throw some exceptions, eq. error: cannot divide by zero, using try catch, this calculator is using the mvc pattern, can you insert switch in try catch?
I have tried but the tetx display field keeps reading infinity instead of throwing the exception which is of course incorrect so its not picking up the exception.
