Pour convertir un Date<\/code> s'opposer \u00e0 LocalDate<\/code> ou LocalDateTime<\/code> et vice versa en Java, vous pouvez utiliser le java.time<\/code> package introduit dans Java 8. Voici un guide d\u00e9taill\u00e9 sur la fa\u00e7on d\u2019effectuer ces conversions\u00a0:<\/p>\n\n\n\n

1. Conversion Date<\/code> \u00e0 LocalDate<\/code><\/h3>\n\n\n\n

En utilisant Instant<\/code> et ZoneId<\/code><\/strong>:<\/p>\n\n\n\n

    \n
  • Tout d'abord, convertissez le Date<\/code> \u00e0 un Instant<\/code>.<\/li>\n\n\n\n
  • Ensuite, utilisez le Instant<\/code> cr\u00e9er un LocalDate<\/code> avec le d\u00e9sir\u00e9 ZoneId<\/code>.<\/li>\n<\/ul>\n\n\n\n
    import java.time.Instant;\nimport java.time.LocalDate;\nimport java.time.ZoneId;\nimport java.util.Date;\n\npublic class DateToLocalDate {\n    public static void main(String[] args) {\n        Date date = new Date(); \/\/ current date\n        Instant instant = date.toInstant();\n        LocalDate localDate = instant.atZone(ZoneId.systemDefault()).toLocalDate();\n        \n        System.out.println("Date: " + date);\n        System.out.println("LocalDate: " + localDate);\n    }\n}\n<\/code><\/pre><\/div>\n\n\n\n
      <\/ol>\n\n\n\n
      2. Conversion LocalDate<\/code> \u00e0 Date<\/code><\/h3>\n\n\n\n

      • Convertir le LocalDate<\/code> \u00e0 un ZonedDateTime<\/code> avec le d\u00e9sir\u00e9 ZoneId<\/code>.<\/li>\n\n\n\n
      • Ensuite, convertissez le ZonedDateTime<\/code> \u00e0 un Instant<\/code> et utilisez-le pour cr\u00e9er un Date<\/code>.<\/li>\n<\/ul>\n\n\n\n
        import java.time.LocalDate;\nimport java.time.ZoneId;\nimport java.time.ZonedDateTime;\nimport java.util.Date;\n\npublic class LocalDateToDate {\n    public static void main(String[] args) {\n        LocalDate localDate = LocalDate.now(); \/\/ current date\n        ZonedDateTime zonedDateTime = localDate.atStartOfDay(ZoneId.systemDefault());\n        Date date = Date.from(zonedDateTime.toInstant());\n        \n        System.out.println("LocalDate: " + localDate);\n        System.out.println("Date: " + date);\n    }\n}\n<\/code><\/pre><\/div>\n\n\n\n
        3. Conversion Date<\/code> \u00e0 LocalDateTime<\/code><\/h3>\n\n\n\n
        En utilisant Instant<\/code> et ZoneId<\/code><\/strong>:<\/p>\n\n\n\n

          4. Conversion LocalDateTime<\/code> \u00e0 Date<\/code><\/h3>\n\n\n\n
