I verified the comparing of Java, which will check the type first. e.g. new int[2][][].equals(new int[2][]) // false new int[2].equals(new long[2]) // false

If not same, the comparing result should be 'false'. Cheers, Daniel.Sun 在 "bo zhang [via Groovy]" <ml-node+[hidden email]>，2016年11月3日 06:53写道： I'm afraid it's not a bug. Actually, `def a=new int[2][]` means that a is an array of two null pointers with type "int []", and `def b=new int[2][][]` means that b is an array of two null pointers with type "int[][]", it seems that they should be equal. See https://github.com/groovy/groovy-core/blob/master/src/test/groovy/ArrayTest.groovy#L198 [http://groovy.329449.n5.nabble.com/attachment/5736458/0/QQ20161103-0%402x.png] 2016-10-30 18:50 GMT+08:00 Daniel.Sun <[hidden email]>: Hi Jochen, I create JIRA issue GROOVY-7983(https://issues.apache.org/jira/browse/GROOVY-7983) to track the issue. BTW, the code in the email should be corrected as follow: def a = new int[2][] def b = new int[2][][] assert a == b // expect faling Cheers, Daniel.Sun -- View this message in context: http://groovy.329449.n5.nabble.com/An-issue-about-comparing-arrays-tp5736379p5736398.html Sent from the Groovy Dev mailing list archive at Nabble.com. ________________________________ If you reply to this email, your message will be added to the discussion below: http://groovy.329449.n5.nabble.com/An-issue-about-comparing-arrays-tp5736379p5736458.html To unsubscribe from An issue about comparing arrays, click here.
