java的方法(类似与C语言函数)

package www.nihao;
import java.util.Scanner;
public class demo02 {
    public static void main(String[] args) {
        //main方法
         Scanner scanner = new Scanner(System.in);
        System.out.println("请输入X的值:");
         int x=scanner.nextInt();
        System.out.println("请输入Y的值:");
         int y=scanner.nextInt();
         int sum = add(x,y);
         System.out.println("调用方法后:"+"x="+x+"y="+y+"结果为:"+sum);
         scanner.close();
    }
    public static int  add (int a,int b)
    {
        return a+b;
    }

}
