Examples of com.ibm.icu.text.DateFormat.format()

com.ibm.icu.text.DateFormat.format()
Overrides Format. Formats a time object into a time string. Examples of time objects are a time value expressed in milliseconds and a Date object. @param obj must be a Number or a Date or a Calendar. @param toAppendTo the string buffer for the returning time string. @return the formatted time string. @param fieldPosition keeps track of the position of the fieldwithin the returned string. On input: an alignment field, if desired. On output: the offsets of the alignment field. For example, given a time text "1996.07.10 AD at 15:08:56 PDT", if the given fieldPosition is DateFormat.YEAR_FIELD, the begin index and end index of fieldPosition will be set to 0 and 4, respectively. Notice that if the same time field appears more than once in a pattern, the fieldPosition will be set for the first occurence of that time field. For instance, formatting a Date to the time string "1 PM PDT (Pacific Daylight Time)" using the pattern "h a z (zzzz)" and the alignment field DateFormat.TIMEZONE_FIELD, the begin index and end index of fieldPosition will be set to 5 and 8, respectively, for the first occurence of the timezone pattern character 'z'. @see java.text.Format @stable ICU 2.0
