Java编程算法基础---使用大整数

package NO5;

import java.math.BigInteger;

public class Test12 {

	

	public static void main(String[] args) {
		// TODO Auto-generated method stub
        //BigInteger a = BigInteger.ONE;   
		BigInteger a = BigInteger.valueOf(1);
        for(int i = 1; i <=10;i++){
        	a = a.multiply(BigInteger.valueOf(i));
            //System.out.println(a);
        }
		System.out.println(a);
		
	}

}
