StringBuffer类型强转Integer类型报错，求助
public static void main(String[] args) {
Calendar c = Calendar.getInstance();
StringBuffer sb=new StringBuffer();
sb.append(c.get(Calendar.YEAR));
sb.append(c.get(Calendar.MONTH)+1);
sb.append(c.get(Calendar.DAY_OF_MONTH));
sb.append(c.get(Calendar.HOUR_OF_DAY));
sb.append(c.get(Calendar.MINUTE));
sb.append(c.get(Calendar.SECOND));
Integer time=Integer.parseInt(sb.toString()); //报错
System.out.println(time);
} integer StringBuffer 强转
[解决办法]
用long类型
[解决办法]
12位数字已经超出int的范围了
[解决办法]
public static int parseInt(String s) throws NumberFormatException {
return parseInt(s,10);
}
上面是源码，最大10位，你的12，所有报错，改为
Long time=Long.parseLong(sb.toString());
[解决办法]
超过范围了 结果2013328145522 已经13位了
