== Why is this an issue?
|
|
|
|
Placing the array designators `[]` after the type helps maintain backward compatibility with older versions of the Java SE platform.
|
|
This syntax contributes to better readability as it becomes easier to distinguish between array types and non-array types.
|
|
It helps convey the intention of the method to both the developer implementing it and the developer using it.

=== Noncompliant code example
|
|
[source,java,diff-id=1,diff-type=noncompliant]
|
|
----
|
|
public class Cube {
|
|
private int magicNumbers[] = { 42 }; // Noncompliant
|
|
public int getVector()[] { /* ... */ } // Noncompliant
|
|
public int[] getMatrix()[] { /* ... */ } // Noncompliant
|
|
}
|
|

|
=== Compliant solution
|
|
[source,java,diff-id=1,diff-type=compliant]
|
|
----
|
|
public class Cube {
|
|
private int[] magicNumbers = { 42 }; // Compliant
|
|
public int[] getVector() { /* ... */ } // Compliant
|
|
public int[][] getMatrix() { /* ... */ } // Compliant
|
|
}
