将数字转换为不同的基数后:
String thirteenAsBase36 = Long.toString(13, 36);
如何将字符串转换回正常的以 10 为基数的数字?
Long thirteenAsBase10 = ?
long parseLong(String s, int radix)
throws NumberFormatException

Long thirteenAsBase10;
try
{
thirteenAsBase10 = Long.parseLong(thirteenAsBase36, 36);
}
catch ( NumberFormatException e )
{
System.out.println("Oops");
}
您的第一个想法应该始终是:阅读 JavaDocs。
