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 stubScanner 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 ) );}}}
