//方法重载例子

public class Sum {

    public static void main(String[] args) {

    //需求1

        int sum1 = getSum(10, 10);

        System.out.println("需求1的和：" + sum1);



    //需求2

        double sum2 = getSum(10.0, 10.0);

        System.out.println("需求2的和：" + sum2);



    //需求3

        int sum3 = getSum(10, 10, 10);

        System.out.println("需求3：" + sum3);

    }



    //需求1：计算整型a+b的和

    public static int getSum(int a, int b){

        return a+b;

    }



    //计算双精度浮点型a+b的和

    public static double getSum(double a, double b){

        return a+b;

    }



    //计算整型a+b+c的和

    public static int getSum(int a, int b, int c){

        return a+b+c;

    }

}

运行结果
