JAVA时间戳格式化为正常日期字符串操作

Long timeStamp = System.currentTimeMillis(); //获取当前时间戳

SimpleDateFormat sdf=new SimpleDateFormat(“yyyy-MM-dd HH:mm:ss”);

String sd = sdf.format(Long.parseLong(String.valueOf(timeStamp)));

String sd2 = sdf.format(new Date(Long.parseLong(String.valueOf(timeStamp))));

String sd3 = sdf.format(timeStamp);

System.out.println(“格式化结果：” + sd);

System.out.println(“格式化结果：” + sd2);

System.out.println(“格式化结果：” + sd3);
