Java 中带参带返回值方法的使用

import java.util.Arrays;

public class HelloWorld 
{
    public static void main(String[] args)
    {
        HelloWorld hello = new HelloWorld();
        String i = hello.show("Dragon");
        System.out.println(i);
    }
    public String show(String name)
    {
        return "Welcome," + name;
    }
}
输出：Welcome,Dragon
