当我保存数据的时候我输入的移动设备没有像1234567891那样保存得当，但当我插入随机mno为4342432435时，它在线程"AWT-EventQueue-0" java.lang.NumberFormatException: For input string: "4342432435"中给出了错误，即出错

答案 0 :(得分：6)
Jigar Joshi已经解释了为什么你首先得到例外，但我个人会避免解析那个开头的数字......你将失去有关重要前导零的信息。例如，我在英国的家庭电话号码以“0797”开头 - 如果您尝试在没有0的情况下拨号，则会失败。
同样，“00”通常用作拨打国际号码的“+”等价物。
基本上，我将数字存储为字符串而不是整数。
答案 1 :(得分：3)
因为4342432435超出int的范围。使用长字段和
Long.parseLong(someString);
答案 2 :(得分：0)
4342432435大于32位int的最大值。
答案 3 :(得分：0)
给定的数字必须在int范围内，否则会出现此错误。
