关于Java版本中Illegal format argument index = 0报错得问题

[beadle1020]

报错： Exception in thread "main" java.util.IllegalFormatArgumentIndexException: Illegal format argument index = 0 at java.base/java.util.Formatter$FormatSpecifier.index(Formatter.java:2803) at java.base/java.util.Formatter$FormatSpecifier.(Formatter.java:2872) at java.base/java.util.Formatter.parse(Formatter.java:2729) at java.base/java.util.Formatter.format(Formatter.java:2671) at java.base/java.util.Formatter.format(Formatter.java:2625) at java.base/java.lang.String.format(String.java:3290) at toolgood.words.internals.BaseMatch.MatchKeywordBuild(BaseMatch.java:188) at toolgood.words.internals.BaseMatch.SetKeywords(BaseMatch.java:362) at toolgood.words.DemoApplication.test_StringMatch(DemoApplication.java:348) at toolgood.words.DemoApplication.main(DemoApplication.java:35)

原因分析：主要是因为在BestMatch中，stringBuilder.append("%" + parameterIndex + "$s");格式化索引的问题，应该从1开始，而不是从零。 解决：改成stringBuilder.append("%" + (parameterIndex+1) + "$s");

有没有测试例子，目前，本人java环境用的比较少。。。
