bigintegerdemo.java

一些java高级源代码

package adv.string;

import java.math.BigInteger;

public class BigIntegerDemo {

	public static void main(String[] args) {
		BigInteger bi1 = new BigInteger("123456789123456789123456789123456789");
		BigInteger bi2 = new BigInteger("987654321987654321987654321987654321");
		BigInteger bi3 = bi1.add(bi2);
		
		System.out.println(bi3);
		System.out.println(bi3.toString(2));
	}
}
