Please review this PR and [CSR](https://bugs.openjdk.org/browse/JDK-8314607) which clarifies the behavior of patterns in regards to the max integer digits in j.text.DecimalFormat.
The current specification (of `applyPattern`) states that patterns do not set the value of max integer digits. This is incorrect, these methods/constructors do set a value for the max integer digits. If the pattern is in scientific notation, the max integer digits value is derived from the pattern. Otherwise, the pattern is ignored, and the limit is set to `Integer.MAX_VALUE`. See below, DecimalFormat df = new DecimalFormat(); df.applyPattern("000.000E0"); df.getMaximumIntegerDigits(); // ==> 3 df.applyPattern("000.000"); df.getMaximumIntegerDigits(); // ==> 2147483647 DecimalFormat df = new DecimalFormat("000.000"); df.getMaximumIntegerDigits(); // ==> 2147483647 DecimalFormat df = new DecimalFormat("000.000E0"); df.getMaximumIntegerDigits(); // ==> 3 Method descriptions should be fixed, and the relevant constructors need to mention the behavior as well. ------------- Commit messages: - Include constructors - Re-clarify spec - Init Changes: https://git.openjdk.org/jdk/pull/15349/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=15349&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8314604 Stats: 28 lines in 1 file changed: 22 ins; 0 del; 6 mod Patch: https://git.openjdk.org/jdk/pull/15349.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/15349/head:pull/15349 PR: https://git.openjdk.org/jdk/pull/15349
