除法"); int method = sc.nextInt(); switch (method) { case 1: System.out.println("请输入第1个数:"); double a1 = sc.nextDouble(); System.out.println("请输入第2个数:"); double a2 = sc.nextDouble(); System.out.println("运算结果为:"+c.add(a1, a2)); break; case 2: System....
double result; switch (operator) { case "+": result = num1 + num2; break; case "-": result = num1 - num2; break; case "*": result = num1 * num2; break; case "/": if (num2 != 0) { result = num1 / num2; } else { System.out.println("除数不能为0"); ...
In this article, we will learn to create a basic calculator using Java. With a basic calculator, we can add, subtract, multiply, or divide two numbers. This is done using a switch case. A program that demonstrates this is given as follows ? Problem Statement Write a program in Java to...
switch (oper) { case '+': res = num1 + num2; break; case'_': res = num2 - num1;//注意顺序 break; case '*': res = num1 * num2; break; case '/': res = num2 / num1; break; default: break; } return res; }
switch (operator) { case '+': System.out.println("结果为:" + (num1 + num2)); break; case '-': System.out.println("结果为:" + (num1 - num2)); break; case '': System.out.println("结果为:" + (num1 num2)); break; ...
In this program, we will create a simple calculator to perform addition, subtraction, multiplication, and division operations using a switch case. Program/Source Code: The source code tocreate a simple calculator using the switch caseis given below. The given program is compiled and executed succe...
Scanner reader=newScanner(System.in);while((str=reader.nextLine())!=null) { k=str.charAt(1); x=Integer.parseInt(String.valueOf(str.charAt(0))); y=Integer.parseInt(String.valueOf(str.charAt(2)));switch(k) {case'+': System.out.printf("%d\n",x+y);break;case'-': ...
