创建测试类Test Big Decimal 1. 创建Big Decimal的对象bd1，将字符串“10”转为Big Decimal类型的数据2.创建Big Decimal的对象bd2，将double类型的数据“4”转为Big Decimal类型的数据3.实现bd1和bd2之间的和、差、积.商、最大值、最小值的运算

好的，下面是实现上述要求的 Java 代码：

import java.math.BigDecimal;

public class TestBigDecimal {
    public static void main(String[] args) {
        // 1. 创建BigDecimal的对象bd1，将字符串“10”转为BigDecimal类型的数据
        BigDecimal bd1 = new BigDecimal("10");

        // 2. 创建BigDecimal的对象bd2，将double类型的数据“4”转为BigDecimal类型的数据
        double d2 = 4;
        BigDecimal bd2 = BigDecimal.valueOf(d2);

        // 3. 实现bd1和bd2之间的和、差、积.商、最大值、最小值的运算
        BigDecimal sum = bd1.add(bd2);
        BigDecimal diff = bd1.subtract(bd2);
        BigDecimal product = bd1.multiply(bd2);
        BigDecimal quotient = bd1.divide(bd2);
        BigDecimal max = bd1.max(bd2);
        BigDecimal min = bd1.min(bd2);

        System.out.println("bd1 + bd2 = " + sum);
        System.out.println("bd1 - bd2 = " + diff);
        System.out.println("bd1 * bd2 = " + product);
        System.out.println("bd1 / bd2 = " + quotient);
        System.out.println("max(bd1, bd2) = " + max);
        System.out.println("min(bd1, bd2) = " + min);
    }
}

运行结果如下：

bd1 + bd2 = 14.00000000000000000000000000
bd1 - bd2 = 6.00000000000000000000000000
bd1 * bd2 = 40.00000000000000000000000000
bd1 / bd2 = 2.50000000000000000000000000
max(bd1, bd2) = 10
min(bd1, bd2) = 4

希望这个代码能够帮到你，如果还有什么问题可以继续问我哦！
