Example 41 with DecimalFormat

use of android.icu.text.DecimalFormat in project j2objc by google.

the class MyNumberFormat method Test4099404.

/**
 * Tests all different comments.
 * Response to some comments :
 * [1] DecimalFormat.parse API documentation is more than just one line.
 * This is not a reproducable doc error in 116 source code.
 * [2] See updated javadoc.
 * [3] Fixed.
 * [4] NumberFormat.parse(String, ParsePosition) : If parsing fails,
 * a null object will be returned.  The unchanged parse position also
 * reflects an error.
 * NumberFormat.parse(String) : If parsing fails, an ParseException
 * will be thrown.
 * See updated javadoc for more details.
 * [5] See updated javadoc.
 * [6] See updated javadoc.
 * [7] This is a correct behavior if the DateFormat object is linient.
 * Otherwise, an IllegalArgumentException will be thrown when formatting
 * "January 35".  See GregorianCalendar class javadoc for more details.
