Question

用重载函数实现两个int的和,两个float的和,两个double的和

Answer 1

package test.alarm;

public class Test
{

/**
 * @Description: TODO
 * @param @param args
 * @return void
 * @throws
 * @author jyj
 */
public static void main(String[] args)
{
    System.out.println(sum(1, 2));
    System.out.println(sum(1f, 2f));
    System.out.println(sum(1d, 2d));

}

public static int sum(int a, int b)
{
    return a + b;
}

public static float sum(float a, float b)
{
    return a + b;
}

public static double sum(double a, double b)
{
    return a + b;
}

}

我用的java ，这是java重构代码，仅供参考
