the class LocalTime method with.

/**
     * Returns a copy of this time with the specified field set to a new value.
     * <p>
     * This returns a {@code LocalTime}, based on this one, with the value
     * for the specified field changed.
     * This can be used to change any supported field, such as the hour, minute or second.
     * If it is not possible to set the value, because the field is not supported or for
     * some other reason, an exception is thrown.
     * <p>
     * If the field is a {@link ChronoField} then the adjustment is implemented here.
     * The supported fields behave as follows:
     * <ul>
     * <li>{@code NANO_OF_SECOND} -
     *  Returns a {@code LocalTime} with the specified nano-of-second.

     * <li>{@code NANO_OF_DAY} -
     *  Returns a {@code LocalTime} with the specified nano-of-day.
     *  This completely replaces the time and is equivalent to {@link #ofNanoOfDay(long)}.
     * <li>{@code MICRO_OF_SECOND} -
     *  Returns a {@code LocalTime} with the nano-of-second replaced by the specified
     *  micro-of-second multiplied by 1,000.
     *  The hour, minute and second will be unchanged.
     * <li>{@code MICRO_OF_DAY} -
     *  Returns a {@code LocalTime} with the specified micro-of-day.
     *  This completely replaces the time and is equivalent to using {@link #ofNanoOfDay(long)}
     *  with the micro-of-day multiplied by 1,000.
     * <li>{@code MILLI_OF_SECOND} -
     *  Returns a {@code LocalTime} with the nano-of-second replaced by the specified
     *  milli-of-second multiplied by 1,000,000.
     *  The hour, minute and second will be unchanged.
     * <li>{@code MILLI_OF_DAY} -

     *  This completely replaces the time and is equivalent to using {@link #ofNanoOfDay(long)}
     *  with the milli-of-day multiplied by 1,000,000.

     *  The second-of-minute and nano-of-second will be unchanged.
     * <li>{@code HOUR_OF_AMPM} -
     *  Returns a {@code LocalTime} with the specified hour-of-am-pm.
     *  The AM/PM, minute-of-hour, second-of-minute and nano-of-second will be unchanged.
     * <li>{@code CLOCK_HOUR_OF_AMPM} -
     *  Returns a {@code LocalTime} with the specified clock-hour-of-am-pm.
     *  The AM/PM, minute-of-hour, second-of-minute and nano-of-second will be unchanged.
     * <li>{@code HOUR_OF_DAY} -

     * All other {@code ChronoField} instances will throw an {@code UnsupportedTemporalTypeException}.
     * <p>
     * If the field is not a {@code ChronoField}, then the result of this method

Example 3 with ChronoField

use of java.time.temporal.ChronoField in project jdk8u_jdk by JetBrains.

the class LocalDate method with.

/**
     * Returns a copy of this date with the specified field set to a new value.
     * <p>
     * This returns a {@code LocalDate}, based on this one, with the value
     * for the specified field changed.

     * If it is not possible to set the value, because the field is not supported or for
     * some other reason, an exception is thrown.
     * <p>
     * In some cases, changing the specified field can cause the resulting date to become invalid,
     * such as changing the month from 31st January to February would make the day-of-month invalid.
     * In cases like this, the field is responsible for resolving the date. Typically it will choose
     * the previous valid date, which would be the last valid day of February in this example.
     * <p>
     * If the field is a {@link ChronoField} then the adjustment is implemented here.
     * The supported fields behave as follows:
     * <ul>
     * <li>{@code DAY_OF_WEEK} -
     *  Returns a {@code LocalDate} with the specified day-of-week.
     *  The date is adjusted up to 6 days forward or backward within the boundary
     *  of a Monday to Sunday week.
     * <li>{@code ALIGNED_DAY_OF_WEEK_IN_MONTH} -
     *  Returns a {@code LocalDate} with the specified aligned-day-of-week.
     *  The date is adjusted to the specified month-based aligned-day-of-week.
     *  Aligned weeks are counted such that the first week of a given month starts
     *  on the first day of that month.
     *  This may cause the date to be moved up to 6 days into the following month.
     * <li>{@code ALIGNED_DAY_OF_WEEK_IN_YEAR} -
     *  Returns a {@code LocalDate} with the specified aligned-day-of-week.
     *  The date is adjusted to the specified year-based aligned-day-of-week.
     *  Aligned weeks are counted such that the first week of a given year starts
     *  on the first day of that year.
     *  This may cause the date to be moved up to 6 days into the following year.
     * <li>{@code DAY_OF_MONTH} -
     *  Returns a {@code LocalDate} with the specified day-of-month.
     *  The month and year will be unchanged. If the day-of-month is invalid for the
     *  year and month, then a {@code DateTimeException} is thrown.
     * <li>{@code DAY_OF_YEAR} -
     *  Returns a {@code LocalDate} with the specified day-of-year.
     *  The year will be unchanged. If the day-of-year is invalid for the
     *  year, then a {@code DateTimeException} is thrown.
     * <li>{@code EPOCH_DAY} -
     *  Returns a {@code LocalDate} with the specified epoch-day.
     *  This completely replaces the date and is equivalent to {@link #ofEpochDay(long)}.
     * <li>{@code ALIGNED_WEEK_OF_MONTH} -
     *  Returns a {@code LocalDate} with the specified aligned-week-of-month.
     *  Aligned weeks are counted such that the first week of a given month starts
     *  on the first day of that month.
     *  This adjustment moves the date in whole week chunks to match the specified week.
     *  The result will have the same day-of-week as this date.
     *  This may cause the date to be moved into the following month.
     * <li>{@code ALIGNED_WEEK_OF_YEAR} -
     *  Returns a {@code LocalDate} with the specified aligned-week-of-year.
     *  Aligned weeks are counted such that the first week of a given year starts
     *  on the first day of that year.

     *  This may cause the date to be moved into the following year.
     * <li>{@code MONTH_OF_YEAR} -
     *  Returns a {@code LocalDate} with the specified month-of-year.
     *  The year will be unchanged. The day-of-month will also be unchanged,
     *  unless it would be invalid for the new month and year. In that case, the
     *  day-of-month is adjusted to the maximum valid value for the new month and year.
     * <li>{@code PROLEPTIC_MONTH} -
     *  Returns a {@code LocalDate} with the specified proleptic-month.
     *  The day-of-month will be unchanged, unless it would be invalid for the new month
     *  and year. In that case, the day-of-month is adjusted to the maximum valid value
     *  for the new month and year.
     * <li>{@code YEAR_OF_ERA} -

     *  The era and month will be unchanged. The day-of-month will also be unchanged,
     *  unless it would be invalid for the new month and year. In that case, the

     * <li>{@code YEAR} -
     *  Returns a {@code LocalDate} with the specified year.
     *  The month will be unchanged. The day-of-month will also be unchanged,
     *  unless it would be invalid for the new month and year. In that case, the
