hdu 1002 A + B Problem II ( JAVA大数)

JAVA的大数很强大的，才学习的，就做了道 A + B 的水题。

 

import java.math.BigInteger;
import java.util.Scanner;

public class Main {
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner cin = new Scanner ( System.in );
		int Case;
		BigInteger a, b;
		
		Case = cin.nextInt();
		for ( int cnt = 1; cnt <= Case; ++cnt ) {
			if ( cnt != 1 ) System.out.println ( );
			a = cin.nextBigInteger();
			b = cin.nextBigInteger();
			
			System.out.println ( "Case " + cnt + ":" );
			System.out.println ( a + " + " + b + " = " + a.add ( b ) );
		}

	}
