Example #2: Write a Java Code to Make Simple Calculator using switch statement (by passing value)

Asks the user to enter two numbers then chose one of the operator (+,-,*,/)then using the switch statement execute and show the result.

Hint ( if,else-if):

if (operator == '+')

 value = firstNum + secondNum;

 else if (operator == '-')

 value = firstNum - secondNum;

 else if (operator == '*' )

 value = firstNum * secondNum;

 else if (operator == '/' )

 value = firstNum / secondNum;

 else {

 System.out.println("Unknown operator: " + operator); 

 }

Example #3: Write a Java Code using switch statement (by passing value)
