Java UNIX时间转换代码详解编程语言

public static String toLocalTime(String unix) { 
    Long timestamp = Long.parseLong(unix) * 1000; 
    String date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new java.util.Date(timestamp)); 
    return date; 
} 
 
public static String toUnixTime(String local){ 
    SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
    String unix = ""; 
    try { 
        unix = df.parse(local).getTime() + ""; 
    } catch (ParseException e) { 
        e.printStackTrace(); 
    } 
    return unix;
