How to find out if the material is in this array?

Answer 1

How to find it in an array?

 for (Material m : blockedlevel1) { if (m.equals(searchedMaterial)) { // assuming that equals() was overriden // found it! do something with it break; } } 

Answer 2

If you need an easy way to check if an element is part of a collection, you should probably consider another data structure such as Set (and use contains ()). With an array, you can only iterate over elements and compare them.

Answer 3

How about searching with the Arrays class?

See Arrays # binary search

Or as someone suggested, turn your array into List and use contains () . Remember that you may need to override the Material # equals method.
