解析十进制字符串以用Java创建BigInteger
要解析十进制字符串以创建BigInteger，只需在BigInteger中设置十进制字符串即可。
这是我们的BigInteger。
BigInteger one; String decStr = "687879"; one = new BigInteger(decStr);
让我们看另一个例子-
示例
import java.math.*;
public class Demo {
public static void main(String[] args) {
BigInteger one, two;
String decStr = "4373427";
one = new BigInteger("250");
two = new BigInteger(decStr);
System.out.println("Result (BigInteger) : " +one);
System.out.println("Result (Parsing Decimal String) : " +two);
}
}输出结果
Result (BigInteger) : 250 Result (Parsing Decimal String) : 4373427
