- Here thr____Calculator.java, to accept an expression as astring in which the operands and operator are separated by zero or more spaces.For example, 3+4 and 3 + 4 are acceptable expressions. Here is a sample run:++PROGRAMMING LANGUAGE: C++ Is it possible to overload the ‘+’ operator for data type int?(Evaluate expression) Modify Listing 20.12, EvaluateExpression.java, to addoperators ^ for exponent and % for remainder. For example, 3 ^ 2 is 9 and 3% 2 is 1. The ^ operator has the highest precedence and the % operator has thesame precedence as the * and / operators. Your program should prompt theuser to enter an expression. Here is a sample run of the program: Enter an expression: (5 * 2 ^ 3 + 2 * 3 % 2) * 4(5 * 2 ^ 3 + 2 * 3 % 2) * 4 = 160 Here is the Listing 20.12 to modify: import java.util.Stack; public class EvaluateExpression { public static void main(String[] args) { // Check number of arguments passed if (args.length != 1) { System.out.println( "Usage: java EvaluateExpression \"expression\""); System.exit(1); } try { System.out.println(evaluateExpression(args[0])); } catch (Exception ex) { System.out.println("Wrong expression: " + args[0]); } } /** Evaluate an expression */ public static int evaluateExpression(String expression) { // Create operandStack to store operands…
