Question
b) Rewrite the code in Figure 2 to include exception handlers to catch arithmetic exception and number format exception which is a simple calculator that can automatically add, multiply, subtract and divide two numbers that have been inputted by users. The arithmetic exception will be displayed with exception message. The number format exception will give error messages for both num1 and num2 if string inputs are not parsed as integer. private String evaluate() { int num1 Integer.parseInt(numStr1); Integer.parseInt(numStr2); int num2 int result = 0; switch (op) { case '+': result = num1 + num2; break; case '-': result = num1 - num2; break; case result = num1 * num2; break; case '/' : result = num1 / num2; } return String.valueOf(result); } }
