Java 算术运算符示例

 Java 运算符

下面的示例显示算术运算符的用法 - 加法 (+)、减法 (-)、乘法 (*)、除法 (/) 和模 (%) 运算符。

public class MyClass {
  public static void main(String[] args) {
    float a = 25f;
    float b = 10f;

    System.out.println("a = "+a+", b = "+b+"\n");

    //添加a和b
    float result_add = a + b;
    System.out.println("a + b = "+result_add);

    //a减去b
    float result_sub = a - b;
    System.out.println("a - b = "+result_sub);

    //a和b相乘
    float result_mul = a * b;
    System.out.println("a * b = "+result_mul);

    //a除以b
    float result_div = a / b;
    System.out.println("a / b = "+result_div);

    //返回除法余数
    float result_modulo = a % b;
    System.out.println("a % b = "+result_modulo);  
  }
}

输出上面的代码将是:

a = 25.0, b = 10.0

a + b = 35.0
a - b = 15.0
a * b = 250.0
a / b = 2.5
a % b = 5.0
