| Generally when comparing arrays for equality, the programmer intends to check |
| that the contents of the arrays are equal rather than that they are actually the |
| same object. But many commonly used equals methods compare arrays for reference |
| equality rather than content equality. These include the instance `.equals()` |
| method, Guava's `com.google.common.base.Objects#equal()`, JDK's |
| `java.util.Objects#equals()`, and Android's |
| `androidx.core.ObjectsCompat#equals()`. |
| |
| If reference equality is needed, `==` should be used instead for clarity. |
| Otherwise, use `java.util.Arrays#equals()` to compare the contents of the |
| arrays. |
