code in java please do not use Array.list to solve this peoblem. i have attached the helpful resources that can be use dto solve this problem down below please check that as well. its in w3schos.com

can use 1) java method

2) java method parameter

3) java method overloading you can apply any of them but not array. list please. let me know if there is any confusion

About This Lab For this lab, we will be creating a simple expression evaluator. We will prompt the user to give us one operator and two operands, then we will process the request. Name Requirements Java file name: ExpressionEvaluator.java Main class name: ExpressionEvaluator Program Requirements The program shall have a separate method for each arithmetic operation (including power, ***) that will return the result le: add(), subtract(), etc... Note: For the power function, you CANNOT use Math.pow(), assume you will never get power = le: "1+2=3" The program shall have a method called isValidOperator that takes the input for the operator and returns a boolean value of whether or not it is a valid operator If the operator was not valid, display an error message and let the program exit Notes/Tips What data type should we be expecting from the user for the operands? THINK: If the user wanted to do 2/3, what data types would we need to provide the correct/expected result? The order in which you accept input does not matter - it is up to your desired design Remember to close the scanner at the end of the program (I will take off points if you do not close the scanner) Sample Output 1 NOTE: Printtines with **** at the start do not need to be in your program They are just auxiliary print statements in the example Welcome to my Expression Evaluator! Enter an operand: 2.3 Enter an operand: 2.5 Enter an operator (+,-,,/,^): + ** Checking if '+' is a valid operator... ** '+' is a valid operator! 2.3 + 2.5 4.8 Ending program... Welcome to my Expression Evaluator! Enter an operand: 2.6 Enter an operand: 9.7 Enter an operator (+,-, *,/,^): ** Checking if 'nuts' is a valid operator... ** "nuts is NOT a valid operator! The operator you entered was not a proper operator Ending program... nuts Helpful Resources Java Methods tutorial Java Method Parameters tutorial Java Method Overloading tutorial
