    public static void main(String[] args) {
        int a = Integer.parseInt(args[0]);
        int b = Integer.parseInt(args[1]);
        int sum  = a + b;
        int prod = a * b;
        int quot = a / b;
        int rem  = a % b;

        System.out.println(a + " + " + b + " = " + sum);
        System.out.println(a + " * " + b + " = " + prod);
        System.out.println(a + " / " + b + " = " + quot);
        System.out.println(a + " % " + b + " = " + rem);
        System.out.println(a + " = " + quot + " * " + b + " + " + rem);
    }
}

答案 0 :(得分:0)

如果是在netbeans上运行,则可以通过右键单击项目,选择属性(位于底部),单击运行类别,然后在Runtime Platform和Main Class下面,将参数传递给main方法。一个用于输入参数的文本字段。


如果您是从命令行调用的,例如运行javac并将其传递为主类名,只需在类名后添加两个命令行参数即可。
