如何安全的将Java String字符串转换为BigDecimal

实现从Java String字符串到BigDecimal的安装转换：

import java.math.BigDecimal;
import java.text.DecimalFormat;
import java.text.NumberFormat;
import java.text.ParsePosition;
import java.util.Locale;

/**

public class DecimalFormatExample {
    public static void main(String[] args) {
        String numStr = "1,000,000,000.999999999999999";
        //Locale in_ID = new Locale("en","US");
        //DecimalFormat nf = (DecimalFormat) NumberFormat.getInstance(in_ID);
        DecimalFormat nf = (DecimalFormat) NumberFormat.getInstance();
        nf.setParseBigDecimal(true);

        BigDecimal bd = (BigDecimal) nf.parse(numStr, new ParsePosition(0));

        System.out.println("bd value : " + bd);
    }
}
