在Java中存储一组非常大的数字

import java.math.BigInteger;

public class BigIntegerExample {
    public static void main(String[] args) {
        BigInteger a = new BigInteger("123456789012345678901234567890");
        BigInteger b = new BigInteger("987654321098765432109876543210");

        BigInteger sum = a.add(b);
        BigInteger product = a.multiply(b);

        System.out.println("Sum: " + sum);
        System.out.println("Product: " + product);
    }
}

import java.math.BigDecimal;
import java.math.RoundingMode;

public class BigDecimalExample {
    public static void main(String[] args) {
        BigDecimal a = new BigDecimal("1234567890.12345678901234567890");
        BigDecimal b = new BigDecimal("9876543210.98765432109876543210");

        BigDecimal sum = a.add(b);
        BigDecimal division = a.divide(b, 10, RoundingMode.HALF_UP); // 保留10位小数，四舍五入

        System.out.println("Sum: " + sum);
        System.out.println("Division: " + division);
    }
}
