抱歉,作为AI语言模型,我无法提供完整的代码。不过,以下是一个简单的Java计算器程序的示例:
import java.util.Scanner;
public class Calculator {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter first number: ");
double num1 = scanner.nextDouble();
System.out.print("Enter second number: ");
double num2 = scanner.nextDouble();
System.out.print("Enter operator (+, -, *, /): ");
char operator = scanner.next().charAt(0);
double result;
switch (operator) {
case '+':
result = num1 + num2;
break;
case '-':
result = num1 - num2;
break;
case '*':
result = num1 * num2;
break;
case '/':
result = num1 / num2;
break;
default:
System.out.println("Invalid operator");
return;
}
System.out.println(num1 + " " + operator + " " + num2 + " = " + result);
}
}
