通过实现Runnable接口，编写程序来创建线程， *并创建两个线程对象，以计算奇数和偶数的总和 (奇数和偶数)1到50岁之间的分别,在屏幕上打印结果。

Write a program to create a thread by implements Runnable Interface, and create two thread objects, to calculate the sum of the odd and even between 1 and 50, respectively, and print the results on the screen.

class mythread2 implements Runnable{
	String m;int sum=0;
	public mythread2(String m) {
     this.m=m;
	}
	public void run() {
			for (int i = 1; i <=50; i+=2) {
				sum+=i;
			}
			System.out.println("1~50的"+m+"和为："+sum);			
	}
	
}
public class t2 {
public static void main(String[] args) {
	mythread2 h1=new mythread2("奇数");
	mythread2 h2=new mythread2("偶数");
	h1.run();
	h2.run();
}
}

The result:

1~50的奇数和为：625
1~50的偶数和为：625
